Wdyt? _6_offset_to_skb_data is for sure not redundant. I don't test a partial fill from the most significant bits in my patch 13. u16_offset_to_skb_data is somewhat similar to fill_32bit_after_spill_64bit, but they aren't exactly the same: the former spills (u32)20 and fills (u16)20 (the same value), while my test spills (u64)0xXXXXXXXX00000000 and fills (u32)0 (the most significant bits are stripped). Maybe u16_offset_to_skb_data is redundant, but more coverage is better than less coverage, isn't it? > > diff --git a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > index 809a09732168..de03e72e07a9 100644 > > --- a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > +++ b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > @@ -217,7 +217,7 @@ __naked void uninit_u32_from_the_stack(void) > > > > SEC("tc") > > __description("Spill a u32 const scalar.

[PATCH net-next v3 0/3] net: gro: reduce extension header parsing overhead

by Richard Gobert

This series attempts to reduce the parsing overhead of IPv6 extension headers in GRO and GSO, by removing extension header specific code and enabling the frag0 fast path. The following changes were made: - Removed some unnecessary HBH conditionals by adding HBH offload to inet6_offloads - Added a utility function to support frag0 fast path in ipv6_gro_receive - Added selftests for IPv6 packets with extension headers in GRO Richard v2 -> v3: - Removed previously added IPv6 extension header length constant and using sizeof(*opth) instead. - Removed unnecessary conditional in gro selftest framework - v2: https://lore.kernel.org/netdev/127b8199-1cd4-42d7-9b2b-875abaad93fe@gmail.c… v1 -> v2: - Added a minimum IPv6 extension header length constant to make code self documenting. - Added new selftest which checks that packets with different extension header payloads do not coalesce. - Added more info in the second commit message regarding the code changes. - v1: https://lore.kernel.org/netdev/f4eff69d-3917-4c42-8c6b-d09597ac4437@gmail.c… Richard Gobert (3): net: gso: add HBH extension header offload support net: gro: parse ipv6 ext headers without frag0 invalidation selftests/net: fix GRO coalesce test and add ext header coalesce tests net/ipv6/exthdrs_offload.c | 11 ++++ net/ipv6/ip6_offload.c | 76 +++++++++++++++++-------- tools/testing/selftests/net/gro.c | 93 +++++++++++++++++++++++++++++-- 3 files changed, 150 insertions(+), 30 deletions(-) -- 2.36.1

[PATCH v4 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH bpf-next 0/2] Annotate kfuncs in .BTF_ids section

by Daniel Xu

This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 2's description.

[PATCHv3 net-next 3/3] selftest/ptp: extend test to include ptp_gettimex64any()

by Mahesh Bandewar

Update testptp.c to exercise the new ptp method gettimex64any(). When only -x option is given the PTP_SYS_OFFSET_EXTENDED or gettimex64() method is exercised while presence of -x with -y will exercise PTP_SYS_OFFSET_ANY or gettimex64any() method. -y option is to choose the timebase from available options of real, mono, or raw.

[RFC PATCH v3 0/3] Add test to verify probe of devices from discoverable busses

by Nícolas F. R. A. Prado

Hi, for this v3 I changed the approach for identifying devices in a stable way from the match fields back to the hardware topology (used in v1). The match fields were proposed as a way to avoid the possible issue of PCI topology being reconfigured, but that wasn't observed on any real system so far. However using match fields does allow for a real issue if an external device similar to an internal one is connected to the system, which results in a change of the match count and therefore a test failure. So using the HW topology was chosen as the most reliable approach. The per-platform device description file now uses YAML following a suggestion from Chris Obbard, and the test script was re-written in python to handle the new YAML format. A second sample board file is also now included for an x86 platform, which contains an USB controller behind a PCI controller, which wasn't possible to describe in v1. Thanks, Nícolas v2: https://lore.kernel.org/all/20231127233558.868365-1-nfraprado@collabora.com v1: https://lore.kernel.org/all/20231024211818.365844-1-nfraprado@collabora.com Original cover letter: This is part of an effort to improve detection of regressions impacting device probe on all platforms. The recently merged DT kselftest [3] detects probe issues for all devices described statically in the DT. That leaves out devices discovered at run-time from discoverable busses. This is where this test comes in. All of the devices that are connected through discoverable busses (ie USB and PCI), and which are internal and therefore always present, can be described in a per-platform file so they can be checked for.

[PATCH] kunit: Protect string comparisons against NULL

by Richard Fitzgerald

Add NULL checks to KUNIT_BINARY_STR_ASSERTION() so that it will fail cleanly if either pointer is NULL, instead of causing a NULL pointer dereference in the strcmp(). A test failure could be that a string is unexpectedly NULL. This could be trapped by KUNIT_ASSERT_NOT_NULL() but that would terminate the test at that point. It's preferable that the KUNIT_EXPECT_STR*() macros can handle NULL pointers as a failure.

[PATCH v2 net-next] selftests/net: change shebang to bash to support "source"

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2]) have a /bin/sh shebang which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to fix the following issues when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 v1 -> v2: - Fix pmtu.sh which has the same issue as unicast_extensions.sh, suggested by Hangbin - Change the style of the "source" line to be consistent with other tests, suggested by Hangbin Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Link: https://lore.kernel.org/all/20231219094856.1740079-1-liuhangbin@gmail.com/ [2] Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/pmtu.sh | 4 ++-- tools/testing/selftests/net/unicast_extensions.sh | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/net/pmtu.sh b/tools/testing/selftests/net/pmtu.sh index 175d3d1d773b..f10879788f61 100755 --- a/tools/testing/selftests/net/pmtu.sh +++ b/tools/testing/selftests/net/pmtu.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # Check that route PMTU values match expectations, and that initial device MTU @@ -198,7 +198,7 @@ # - pmtu_ipv6_route_change # Same as above but with IPv6 -source ./lib.sh +source lib.sh PAUSE_ON_FAIL=no VERBOSE=0 diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..f52aa5f7da52 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project @@ -28,7 +28,7 @@ # These tests provide an easy way to flip the expected result of any # of these behaviors for testing kernel patches that change them. -source ./lib.sh +source lib.sh # nettest can be run from PATH or from same directory as this selftest if ! which nettest >/dev/null; then base-commit: cd4d7263d58ab98fd4dee876776e4da6c328faa3 -- 2.34.1

[PATCH net-next v2 0/3] net: gro: reduce extension header parsing overhead

by Richard Gobert

This series attempts to reduce the parsing overhead of IPv6 extension headers in GRO and GSO, by removing extension header specific code and enabling the frag0 fast path. The following changes were made: - Removed some unnecessary HBH conditionals by adding HBH offload to inet6_offloads - Added a utility function to support frag0 fast path in ipv6_gro_receive - Added selftests for IPv6 packets with extension headers in GRO Richard v1 -> v2: - Added a minimum IPv6 extension header length constant to make code self documenting. - Added new selftest which checks that packets with different extension header payloads do not coalesce. - Added more info in the second commit message regarding the code changes. - v1: https://lore.kernel.org/netdev/f4eff69d-3917-4c42-8c6b-d09597ac4437@gmail.c… Richard Gobert (3): net: gso: add HBH extension header offload support net: gro: parse ipv6 ext headers without frag0 invalidation selftests/net: fix GRO coalesce test and add ext header coalesce tests include/net/ipv6.h | 1 + net/ipv6/exthdrs_offload.c | 11 ++++ net/ipv6/ip6_offload.c | 76 +++++++++++++++++-------- tools/testing/selftests/net/gro.c | 94 +++++++++++++++++++++++++++++-- 4 files changed, 152 insertions(+), 30 deletions(-) -- 2.36.1

[PATCH v10 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks.

(Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation.

The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy().

[PATCH bpf-next 0/2] bpf: add csum/ip_summed fields to __sk_buff

by Menglong Dong

For now, we have to call some helpers when we need to update the csum, such as bpf_l4_csum_replace, bpf_l3_csum_replace, etc. These helpers are not inlined, which causes poor performance. In fact, we can define our own csum update functions in BPF program instead of bpf_l3_csum_replace, which is totally inlined and efficient. However, we can't do this for bpf_l4_csum_replace for now, as we can't update skb->csum, which can cause skb->csum invalid in the rx path with CHECKSUM_COMPLETE mode. What's more, we can't use the direct data access and have to use skb_store_bytes() with the BPF_F_RECOMPUTE_CSUM flag in some case, such as modifing the vni in the vxlan header and the underlay udp header has no checksum. In the first patch, we make skb->csum readable and writable, and we make skb->ip_summed readable. For now, for tc only. With these 2 fields, we don't need to call bpf helpers for csum update any more. In the second patch, we add some testcases for the read/write testing for skb->csum and skb->ip_summed. If this series is acceptable, we can define the inlined functions for csum update in libbpf in the next step.

[PATCH v2 1/1] userfaultfd: fix move_pages_pte() splitting folio under RCU read lock

by Suren Baghdasaryan

While testing the split PMD path with lockdep enabled I've got an "Invalid wait context" error caused by split_huge_page_to_list() trying to lock anon_vma->rwsem while inside RCU read section. The issues is due to move_pages_pte() calling split_folio() under RCU read lock. Fix this by unmapping the PTEs and exiting RCU read section before splitting the folio and then retrying. The same retry pattern is used when locking the folio or anon_vma in this function.

[PATCH 1/1] userfaultfd: fix move_pages_pte() splitting folio under RCU read lock

by Suren Baghdasaryan

While testing the split PMD path with lockdep enabled I've got an "Invalid wait context" error caused by split_huge_page_to_list() trying to lock anon_vma->rwsem while inside RCU read section. The issues is due to move_pages_pte() calling split_folio() under RCU read lock. Fix this by unmapping the PTEs and exiting RCU read section before splitting the folio and then retrying. The same retry pattern is used when locking the folio or anon_vma in this function.

[PATCH v8 00/24] security: Move IMA and EVM to the LSM infrastructure

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> IMA and EVM are not effectively LSMs, especially due to the fact that in the past they could not provide a security blob while there is another LSM active. That changed in the recent years, the LSM stacking feature now makes it possible to stack together multiple LSMs, and allows them to provide a security blob for most kernel objects. While the LSM stacking feature has some limitations being worked out, it is already suitable to make IMA and EVM as LSMs. The main purpose of this patch set is to remove IMA and EVM function calls, hardcoded in the LSM infrastructure and other places in the kernel, and to register them as LSM hook implementations, so that those functions are called by the LSM infrastructure like other regular LSMs. This patch set introduces two new LSMs 'ima' and 'evm', so that functions can be registered to their respective LSM, and removes the 'integrity' LSM. integrity_kernel_module_request() was moved to IMA, since it was related to appraisal. integrity_inode_free() was replaced with ima_inode_free_security() (EVM does not need to free memory). In order to make 'ima' and 'evm' independent LSMs, it was necessary to split integrity metadata used by both IMA and EVM, and to let them manage their own. The special case of the IMA_NEW_FILE flag, managed by IMA and used by EVM, was handled by introducing a new flag in EVM, EVM_NEW_FILE, managed by two additional LSM hooks, evm_post_path_mknod() and evm_file_free(), equivalent to their counterparts ima_post_path_mknod() and ima_file_free(). In addition to splitting metadata, it was decided to embed the full structure into the inode security blob, rather than using a cache of objects and allocating them on demand. This opens for new possibilities, such as improving locking in IMA. Another follow-up change was removing the iint parameter from evm_verifyxattr(), that IMA used to pass integrity metadata to EVM. After splitting metadata, and aligning EVM_NEW_FILE with IMA_NEW_FILE, this parameter was not necessary anymore. The last part was to ensure that the order of IMA and EVM functions is respected after they become LSMs. Since the order of lsm_info structures in the .lsm_info.init section depends on the order object files containing those structures are passed to the linker of the kernel image, and since IMA is before EVM in the Makefile, that is sufficient to assert that IMA functions are executed before EVM ones. The patch set is organized as follows. Patches 1-9 make IMA and EVM functions suitable to be registered to the LSM infrastructure, by aligning function parameters. Patches 10-18 add new LSM hooks in the same places where IMA and EVM functions are called, if there is no LSM hook already. Patches 19-21 introduce the new standalone LSMs 'ima' and 'evm', and move hardcoded calls to IMA, EVM and integrity functions to those LSMs. Patches 22-23 remove the dependency on the 'integrity' LSM by splitting integrity metadata, so that the 'ima' and 'evm' LSMs can use their own. They also duplicate iint_lockdep_annotate() in ima_main.c, since the mutex field was moved from integrity_iint_cache to ima_iint_cache. Patch 24 finally removes the 'integrity' LSM, since 'ima' and 'evm' are now self-contained and independent. The patch set applies on top of lsm/dev, commit 80b4ff1d2c9b ("selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test"). The linux-integrity/next-integrity-testing at commit f17167bea279 ("ima: Remove EXPERIMENTAL from Kconfig") was merged. Changelog: v7: - Use return instead of goto in __vfs_removexattr_locked() (suggested by Casey) - Clarify in security/integrity/Makefile that the order of 'ima' and 'evm' LSMs depends on the order in which IMA and EVM are compiled - Move integrity_iint_cache flags to ima.h and evm.h in security/ and duplicate IMA_NEW_FILE to EVM_NEW_FILE - Rename evm_inode_get_iint() to evm_iint_inode() and ima_inode_get_iint() to ima_iint_inode(), check if inode->i_security is NULL, and just return the pointer from the inode security blob - Restore the non-NULL checks after ima_iint_inode() and evm_iint_inode() (suggested by Casey) - Introduce evm_file_free() to clear EVM_NEW_FILE - Remove comment about LSM_ORDER_LAST not guaranteeing the order of 'ima' and 'evm' LSMs - Lock iint->mutex before reading IMA_COLLECTED flag in __ima_inode_hash() and restored ima_policy_flag check - Remove patch about the hardcoded ordering of 'ima' and 'evm' LSMs in security.c - Add missing ima_inode_free_security() to free iint->ima_hash - Add the cases for LSM_ID_IMA and LSM_ID_EVM in lsm_list_modules_test.c - Mention about the change in IMA and EVM post functions for private inodes v6: - See v7 v5: - Rename security_file_pre_free() to security_file_release() and the LSM hook file_pre_free_security to file_release (suggested by Paul) - Move integrity_kernel_module_request() to ima_main.c (renamed to ima_kernel_module_request()) - Split the integrity_iint_cache structure into ima_iint_cache and evm_iint_cache, so that IMA and EVM can use disjoint metadata and reserve space with the LSM infrastructure - Reserve space for the entire ima_iint_cache and evm_iint_cache structures, not just the pointer (suggested by Paul) - Introduce ima_inode_get_iint() and evm_inode_get_iint() to retrieve respectively the ima_iint_cache and evm_iint_cache structure from the security blob - Remove the various non-NULL checks for the ima_iint_cache and evm_iint_cache structures, since the LSM infrastructure ensure that they always exist - Remove the iint parameter from evm_verifyxattr() since IMA and EVM use disjoint integrity metaddata - Introduce the evm_post_path_mknod() to set the IMA_NEW_FILE flag - Register the inode_alloc_security LSM hook in IMA and EVM to initialize the respective integrity metadata structures - Remove the 'integrity' LSM completely and instead make 'ima' and 'evm' proper standalone LSMs - Add the inode parameter to ima_get_verity_digest(), since the inode field is not present in ima_iint_cache - Move iint_lockdep_annotate() to ima_main.c (renamed to ima_iint_lockdep_annotate()) - Remove ima_get_lsm_id() and evm_get_lsm_id(), since IMA and EVM directly register the needed LSM hooks - Enforce 'ima' and 'evm' LSM ordering at LSM infrastructure level v4: - Improve short and long description of security_inode_post_create_tmpfile(), security_inode_post_set_acl(), security_inode_post_remove_acl() and security_file_post_open() (suggested by Mimi) - Improve commit message of 'ima: Move to LSM infrastructure' (suggested by Mimi) v3: - Drop 'ima: Align ima_post_path_mknod() definition with LSM infrastructure' and 'ima: Align ima_post_create_tmpfile() definition with LSM infrastructure', define the new LSM hooks with the same IMA parameters instead (suggested by Mimi) - Do IS_PRIVATE() check in security_path_post_mknod() and security_inode_post_create_tmpfile() on the new inode rather than the parent directory (in the post method it is available) - Don't export ima_file_check() (suggested by Stefan) - Remove redundant check of file mode in ima_post_path_mknod() (suggested by Mimi) - Mention that ima_post_path_mknod() is now conditionally invoked when CONFIG_SECURITY_PATH=y (suggested by Mimi) - Mention when a LSM hook will be introduced in the IMA/EVM alignment patches (suggested by Mimi) - Simplify the commit messages when introducing a new LSM hook - Still keep the 'extern' in the function declaration, until the declaration is removed (suggested by Mimi) - Improve documentation of security_file_pre_free() - Register 'ima' and 'evm' as standalone LSMs (suggested by Paul) - Initialize the 'ima' and 'evm' LSMs from 'integrity', to keep the original ordering of IMA and EVM functions as when they were hardcoded - Return the IMA and EVM LSM IDs to 'integrity' for registration of the integrity-specific hooks - Reserve an xattr slot from the 'evm' LSM instead of 'integrity' - Pass the LSM ID to init_ima_appraise_lsm() v2: - Add description for newly introduced LSM hooks (suggested by Casey) - Clarify in the description of security_file_pre_free() that actions can be performed while the file is still open v1: - Drop 'evm: Complete description of evm_inode_setattr()', 'fs: Fix description of vfs_tmpfile()' and 'security: Introduce LSM_ORDER_LAST', they were sent separately (suggested by Christian Brauner) - Replace dentry with file descriptor parameter for security_inode_post_create_tmpfile() - Introduce mode_stripped and pass it as mode argument to security_path_mknod() and security_path_post_mknod() - Use goto in do_mknodat() and __vfs_removexattr_locked() (suggested by Mimi) - Replace __lsm_ro_after_init with __ro_after_init - Modify short description of security_inode_post_create_tmpfile() and security_inode_post_set_acl() (suggested by Stefan) - Move security_inode_post_setattr() just after security_inode_setattr() (suggested by Mimi) - Modify short description of security_key_post_create_or_update() (suggested by Mimi) - Add back exported functions ima_file_check() and evm_inode_init_security() respectively to ima.h and evm.h (reported by kernel robot) - Remove extern from prototype declarations and fix style issues - Remove unnecessary include of linux/lsm_hooks.h in ima_main.c and ima_appraise.c Roberto Sassu (24): ima: Align ima_inode_post_setattr() definition with LSM infrastructure ima: Align ima_file_mprotect() definition with LSM infrastructure ima: Align ima_inode_setxattr() definition with LSM infrastructure ima: Align ima_inode_removexattr() definition with LSM infrastructure ima: Align ima_post_read_file() definition with LSM infrastructure evm: Align evm_inode_post_setattr() definition with LSM infrastructure evm: Align evm_inode_setxattr() definition with LSM infrastructure evm: Align evm_inode_post_setxattr() definition with LSM infrastructure security: Align inode_setattr hook definition with EVM security: Introduce inode_post_setattr hook security: Introduce inode_post_removexattr hook security: Introduce file_post_open hook security: Introduce file_release hook security: Introduce path_post_mknod hook security: Introduce inode_post_create_tmpfile hook security: Introduce inode_post_set_acl hook security: Introduce inode_post_remove_acl hook security: Introduce key_post_create_or_update hook ima: Move to LSM infrastructure ima: Move IMA-Appraisal to LSM infrastructure evm: Move to LSM infrastructure evm: Make it independent from 'integrity' LSM ima: Make it independent from 'integrity' LSM integrity: Remove LSM fs/attr.c | 5 +- fs/file_table.c | 3 +- fs/namei.c | 12 +- fs/nfsd/vfs.c | 3 +- fs/open.c | 1 -

[PATCH net-next 0/4] mptcp: add CurrEstab MIB counter

by Matthieu Baerts

This MIB counter is similar to the one of TCP -- CurrEstab -- available in /proc/net/snmp. This is useful to quickly list the number of MPTCP connections without having to iterate over all of them. Patch 1 prepares its support by adding new helper functions: - MPTCP_DEC_STATS(): similar to MPTCP_INC_STATS(), but this time to decrement a counter. - mptcp_set_state(): similar to tcp_set_state(), to change the state of an MPTCP socket, and to inc/decrement the new counter when needed. Patch 2 uses mptcp_set_state() instead of directly calling inet_sk_state_store() to change the state of MPTCP sockets. Patch 3 and 4 validate the new feature in MPTCP "join" and "diag" selftests.

[PATCH v9 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel.

[PATCH net-next] selftests/net: change the shebang of unicast_extensions.sh to bash

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. The shebang of unicast_extensions.sh is /bin/sh which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to suppress the following errors when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Fixes: 0f4765d0b48d ("selftests/net: convert unicast_extensions.sh to run it in unique namespace") Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/unicast_extensions.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..2766990c2b78 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project -- 2.34.1

[PATCH net-next 0/3] net: gro: reduce extension header parsing overhead

by Richard Gobert

This series attempts to reduce parsing overhead of IPv6 extension headers in GRO and GSO, by removing extension header specific code and enabling the frag0 fast path. The following changes were made: - Specific unnecessary HBH conditionals were removed by adding HBH offload to inet6_offloads - Added a utility function to support frag0 fast path in ipv6_gro_receive - Added self-test for IPv6 packets with extension headers in GRO Richard Richard Gobert (3): net: gso: add HBH extension header offload support net: gro: parse ipv6 ext headers without frag0 invalidation selftests/net: fix GRO coalesce test and add ext header coalesce test net/ipv6/exthdrs_offload.c | 11 +++++ net/ipv6/ip6_offload.c | 76 ++++++++++++++++++++---------- tools/testing/selftests/net/gro.c | 78 ++++++++++++++++++++++++++++--- 3 files changed, 134 insertions(+), 31 deletions(-) -- 2.36.1

[PATCH v7 0/9] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table.

[PATCH net-next 0/4] mptcp: cleanup and support more ephemeral ports sockopts

by Matthieu Baerts

Patch 1 is a cleanup one: mptcp_is_tcpsk() helper was modifying sock_ops in some cases which is unexpected with that name. Patch 2 to 4 add support for two socket options: IP_LOCAL_PORT_RANGE and IP_BIND_ADDRESS_NO_PORT. The first one is a preparation patch, the second one adds the support while the last one modifies an existing selftest to validate the new features. Signed-off-by: Matthieu Baerts <matttbe(a)kernel.org> --- Davide Caratti (1): mptcp: don't overwrite sock_ops in mptcp_is_tcpsk() Maxim Galaganov (3): mptcp: rename mptcp_setsockopt_sol_ip_set_transparent() mptcp: sockopt: support IP_LOCAL_PORT_RANGE and IP_BIND_ADDRESS_NO_PORT selftests/net: add MPTCP coverage for IP_LOCAL_PORT_RANGE net/mptcp/protocol.c | 108 +++++++++------------- net/mptcp/sockopt.c | 27 +++++- tools/testing/selftests/net/ip_local_port_range.c | 12 +++ 3 files changed, 79 insertions(+), 68 deletions(-) --- base-commit: 62ed78f3baff396bd928ee77077580c5aa940149 change-id: 20231219-upstream-net-next-20231219-mptcp-sockopts-ephemeral-ports-645522e83161 Best regards, -- Matthieu Baerts <matttbe(a)kernel.org>

[PATCH bpf-next 00/15] Improvements for tracking scalars in the BPF verifier

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> The goal of this series is to extend the verifier's capabilities of tracking scalars when they are spilled to stack, especially when the spill or fill is narrowing. It also contains a fix by Eduard for infinite loop detection and a state pruning optimization by Eduard that compensates for a verification complexity regression introduced by tracking unbounded scalars. These improvements reduce the surface of false rejections that I saw while working on Cilium codebase. Patch 1 (Maxim): Fix for an existing test, it will matter later in the series. Patches 2-3 (Eduard): Fixes for false rejections in infinite loop detection that happen in the selftests when my patches are applied. Patches 4-5 (Maxim): Fix the inconsistency of find_equal_scalars that was possible if 32-bit spills were made. Patches 6-11 (Maxim): Support the case when boundary checks are first performed after the register was spilled to the stack. Patches 12-13 (Maxim): Support narrowing fills. Patches 14-15 (Eduard): Optimization for state pruning in stacksafe() to mitigate the verification complexity regression. veristat -e file,prog,states -f '!states_diff<50' -f '!states_pct<10' -f '!states_a<10' -f '!states_b<10' -C ... * Without patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- ---------------- bpf_xdp.o tail_lb_ipv6 3877 2936 -941 (-24.27%) pyperf180.bpf.o on_event 8422 10456 +2034 (+24.15%) pyperf600.bpf.o on_event 22259 37319 +15060 (+67.66%) pyperf600_iter.bpf.o on_event 400 540 +140 (+35.00%) strobemeta.bpf.o on_event 4702 13435 +8733 (+185.73%) * With patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- -------------- bpf_xdp.o tail_lb_ipv6 3877 2937 -940 (-24.25%) pyperf600_iter.bpf.o on_event 400 500 +100 (+25.00%) Eduard Zingerman (4): bpf: make infinite loop detection in is_state_visited() exact selftests/bpf: check if imprecise stack spills confuse infinite loop detection bpf: Optimize state pruning for spilled scalars selftests/bpf: states pruning checks for scalar vs STACK_{MISC,ZERO} Maxim Mikityanskiy (11): selftests/bpf: Fix the u64_offset_to_skb_data test bpf: Make bpf_for_each_spilled_reg consider narrow spills selftests/bpf: Add a test case for 32-bit spill tracking bpf: Add the assign_scalar_id_before_mov function bpf: Add the get_reg_width function bpf: Assign ID to scalars on spill selftests/bpf: Test assigning ID to scalars on spill bpf: Track spilled unbounded scalars selftests/bpf: Test tracking spilled unbounded scalars bpf: Preserve boundaries and track scalars on narrowing fill selftests/bpf: Add test cases for narrowing fill include/linux/bpf_verifier.h | 2 +- kernel/bpf/verifier.c | 160 +++++- .../bpf/progs/verifier_direct_packet_access.c | 2 +- .../selftests/bpf/progs/verifier_loops1.c | 24 + .../selftests/bpf/progs/verifier_spill_fill.c | 529 +++++++++++++++++- .../testing/selftests/bpf/verifier/precise.c | 6 +- 6 files changed, 677 insertions(+), 46 deletions(-) -- 2.42.1

[PATCH] kunit: Fix some comments which were mistakenly kerneldoc

by David Gow

The KUnit device helpers are documented with kerneldoc in their header file, but also have short comments over their implementation. These were mistakenly formatted as kerneldoc comments, even though they're not valid kerneldoc. It shouldn't cause any serious problems -- this file isn't included in the docs -- but it could be confusing, and causes warnings. Remove the extra '*' so that these aren't treated as kerneldoc.

Trivial fix for out-of-tree build that I wasn't testing previously: 1.

Include $(KHDR_INCLUDES) that's exported by selftests/Makefile, fixes: > In file included from lib/kconfig.c:6: > lib/aolib.h:320:45: warning: ‘struct tcp_ao_add’ declared inside parameter list will not be visible outside of this definition or declaration > 320 | extern int test_prepare_key_sockaddr(struct tcp_ao_add *ao, const char *alg, > | ^~~~~~~~~~ ... 3. While at here, clean-up $(KSFT_KHDR_INSTALL): it's not needed anymore since commit f2745dc0ba3d ("selftests: stop using KSFT_KHDR_INSTALL") 4.

[PATCH v4] tracing/selftests: Add ownership modification tests for eventfs

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> As there were bugs found with the ownership of eventfs dynamic file creation. Add a test to test it. It will remount tracefs with a different gid and check the ownership of the eventfs directory, as well as the system and event directories. It will also check the event file directories. It then does a chgrp on each of these as well to see if they all get updated as expected. Then it remounts the tracefs file system back to the original group and makes sure that all the updated files and directories were reset back to the original ownership.

[PATCH RFC v2 00/22] KVM: arm64: Implement support for SME in non-protected guests

by Mark Brown

This series implements support for SME use in non-protected KVM guests. Much of this is very similar to SVE, the main additional challenge that SME presents is that it introduces two new controls which change the registers seen by guests: - PSTATE.ZA enables the ZA matrix register and, if SME2 is supported, the ZT0 LUT register. - PSTATE.SM enables streaming mode, a new floating point mode which uses the SVE register set with a separately configured vector length. In streaming mode implementation of the FFR register is optional. It is also permitted to build systems which support SME without SVE, in this case when not in streaming mode no SVE registers or instructions are available. Further, there is no requirement that there be any overlap in the set of vector lengths supported by SVE and SME in a system, this is expected to be a common situation in practical systems. Since there is a new vector length to configure we introduce a new feature parallel to the existing SVE one with a new pseudo register for the streaming mode vector length. Due to the overlap with SVE caused by streaming mode rather than finalising SME as a separate feature we use the existing SVE finalisation to also finalise SME, a new define KVM_ARM_VCPU_VEC is provided to help make user code clearer. Finalising SVE and SME separately would introduce complication with register access since finalising SVE makes the SVE regsiters writeable by userspace and doing multiple finalisations results in an error being reported. Dealing with a state where the SVE registers are writeable due to one of SVE or SME being finalised but may have their VL changed by the other being finalised seems like needless complexity with minimal practical utility, it seems clearer to just express directly that only one finalisation can be done in the ABI. We represent the streaming mode registers to userspace by always using the existing SVE registers to access the floating point state, using the larger of the SME and (if enabled for the guest) SVE vector lengths. There are a large number of subfeatures for SME, most of which only offer additional instructions but some of which (SME2 and FA64) add architectural state. The expectation is that these will be configured via the ID registers but since the mechanism for doing this is still unclear the current code enables SME2 and FA64 for the guest if the host supports them regardless of what the ID registers say. Since we do not yet have support for SVE in protected guests and SME is very reliant on SVE this series does not implement support for SME in protected guests. This will be added separately once SVE support is merged into mainline (or along with merging that), there is code for protected guests using SVE in the Android tree. The new KVM_ARM_VCPU_VEC feature and ZA and ZT0 registers have not been added to the get-reg-list selftest, the idea of supporting additional features there without restructuring the program to generate all possible feature combinations has been rejected. I will post a separate series which does that restructuring. I am seeing some test failures currently which I've not got to the bottom of, at this point I'm reasonably sure these are preexisting issues in the kernel which are more apparent in a guest.

[PATCH v2 1/2] kunit: Allow passing function pointer to kunit_activate_static_stub()

by Richard Fitzgerald

Swap the arguments to typecheck_fn() in kunit_activate_static_stub() so that real_fn_addr can be either the function itself or a pointer to that function. This is useful to simplify redirecting static functions in a module. Having to pass the actual function meant that it must be exported from the module. Either making the 'static' and EXPORT_SYMBOL*() conditional (which makes the code messy), or change it to always exported (which increases the export namespace and prevents the compiler inlining a trivial stub function in non-test builds). With the original definition of kunit_activate_static_stub() the address of real_fn_addr was passed to typecheck_fn() as the type to be passed. This meant that if real_fn_addr was a pointer-to-function it would resolve to a ** instead of a *, giving an error like this: error: initialization of ‘int (**)(int)’ from incompatible pointer type ‘int (*)(int)’ [-Werror=incompatible-pointer-types] kunit_activate_static_stub(test, add_one_fn_ptr, subtract_one); | ^~~~~~~~~~~~ ./include/linux/typecheck.h:21:25: note: in definition of macro ‘typecheck_fn’ 21 | ({ typeof(type) __tmp = function; \ Swapping the arguments to typecheck_fn makes it take the type of a pointer to the replacement function. Either a function or a pointer to function can be assigned to that. For example: static int some_function(int x) { /* whatever */ } int (* some_function_ptr)(int) = some_function; static int replacement(int x) { /* whatever */ } Then: kunit_activate_static_stub(test, some_function, replacement); yields: typecheck_fn(typeof(&replacement), some_function); and: kunit_activate_static_stub(test, some_function_ptr, replacement); yields: typecheck_fn(typeof(&replacement), some_function_ptr); The two typecheck_fn() then resolve to: int (*__tmp)(int) = some_function; and int (*__tmp)(int) = some_function_ptr; Both of these are valid. In the first case the compiler inserts an implicit '&' to take the address of the supplied function, and in the second case the RHS is already a pointer to the same type.
