[PATCH v7 0/8] firmware: add partial read support in request_firmware_into_buf

by Scott Branden

This patch series adds partial read support in request_firmware_into_buf. In order to accept the enhanced API it has been requested that kernel selftests and upstreamed driver utilize the API enhancement and so are included in this patch series. Also in this patch series is the addition of a new Broadcom VK driver utilizing the new request_firmware_into_buf enhanced API. Further comment followed to add IMA support of the partial reads originating from request_firmware_into_buf calls. Changes from v6: - update ima_post_read_file check on IMA_FIRMWARE_PARTIAL_READ - adjust new driver i2c-slave-eeprom.c use of request_firmware_into_buf - remove an extern Changes from v5: - add IMA FIRMWARE_PARTIAL_READ support - change kernel pread flags to enum - removed legacy support from driver - driver fixes Changes from v4: - handle reset issues if card crashes - allow driver to have min required msix - add card utilization information Changes from v3: - fix sparse warnings - fix printf format specifiers for size_t - fix 32-bit cross-compiling reports 32-bit shifts - use readl/writel,_relaxed to access pci ioremap memory, removed memory barriers and volatile keyword with such change - driver optimizations for interrupt/poll functionalities Changes from v2: - remove unnecessary code and mutex locks in lib/test_firmware.c - remove VK_IOCTL_ACCESS_BAR support from driver and use pci sysfs instead - remove bitfields - remove Kconfig default m - adjust formatting and some naming based on feedback - fix error handling conditions - use appropriate return codes - use memcpy_toio instead of direct access to PCIE bar Scott Branden (8): fs: introduce kernel_pread_file* support firmware: add offset to request_firmware_into_buf test_firmware: add partial read support for request_firmware_into_buf firmware: test partial file reads of request_firmware_into_buf bcm-vk: add bcm_vk UAPI misc: bcm-vk: add Broadcom VK driver MAINTAINERS: bcm-vk: add maintainer for Broadcom VK Driver ima: add FIRMWARE_PARTIAL_READ support MAINTAINERS | 7 + drivers/base/firmware_loader/firmware.h | 5 + drivers/base/firmware_loader/main.c | 59 +- drivers/i2c/i2c-slave-eeprom.c | 4 +- drivers/misc/Kconfig | 1 + drivers/misc/Makefile | 1 + drivers/misc/bcm-vk/Kconfig | 29 + drivers/misc/bcm-vk/Makefile | 11 + drivers/misc/bcm-vk/bcm_vk.h | 408 +++++ drivers/misc/bcm-vk/bcm_vk_dev.c | 1312 +++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.c | 1438 +++++++++++++++++ drivers/misc/bcm-vk/bcm_vk_msg.h | 201 +++ drivers/misc/bcm-vk/bcm_vk_sg.c | 271 ++++ drivers/misc/bcm-vk/bcm_vk_sg.h | 60 + drivers/misc/bcm-vk/bcm_vk_tty.c | 352 ++++ drivers/soc/qcom/mdt_loader.c | 7 +- fs/exec.c | 101 +- include/linux/firmware.h | 8 +- include/linux/fs.h | 30 + include/uapi/linux/misc/bcm_vk.h | 99 ++ lib/test_firmware.c | 144 +- security/integrity/ima/ima_main.c | 24 +- .../selftests/firmware/fw_filesystem.sh | 80 + 23 files changed, 4598 insertions(+), 54 deletions(-) create mode 100644 drivers/misc/bcm-vk/Kconfig create mode 100644 drivers/misc/bcm-vk/Makefile create mode 100644 drivers/misc/bcm-vk/bcm_vk.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_dev.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_msg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.c create mode 100644 drivers/misc/bcm-vk/bcm_vk_sg.h create mode 100644 drivers/misc/bcm-vk/bcm_vk_tty.c create mode 100644 include/uapi/linux/misc/bcm_vk.h -- 2.17.1

[PATCH v4 kunit-next 0/2] kunit: extend kunit resources API

by Alan Maguire

A recent RFC patch set [1] suggests some additional functionality may be needed around kunit resources. It seems to require 1. support for resources without allocation 2. support for lookup of such resources 3. support for access to resources across multiple kernel threads The proposed changes here are designed to address these needs. The idea is we first generalize the API to support adding resources with static data; then from there we support named resources. The latter support is needed because if we are in a different thread context and only have the "struct kunit *" to work with, we need a way to identify a resource in lookup. [1] https://lkml.org/lkml/2020/2/26/1286 Changes since v3: - removed unused "init" field from "struct kunit_resources" (Brendan) Changes since v2: - moved a few functions relating to resource retrieval in patches 1 and 2 into include/kunit/test.h and defined as "static inline"; this allows built-in consumers to use these functions when KUnit is built as a module Changes since v1: - reformatted longer parameter lists to have one parameter per-line (Brendan, patch 1) - fixed phrasing in various comments to clarify allocation of memory and added comment to kunit resource tests to clarify why kunit_put_resource() is used there (Brendan, patch 1) - changed #define to static inline function (Brendan, patch 2) - simplified kunit_add_named_resource() to use more of existing code for non-named resource (Brendan, patch 2) Alan Maguire (2): kunit: generalize kunit_resource API beyond allocated resources kunit: add support for named resources Alan Maguire (2): kunit: generalize kunit_resource API beyond allocated resources kunit: add support for named resources include/kunit/test.h | 210 +++++++++++++++++++++++++++++++++++++++------- lib/kunit/kunit-test.c | 111 +++++++++++++++++++----- lib/kunit/string-stream.c | 14 ++-- lib/kunit/test.c | 171 ++++++++++++++++++++++--------------- 4 files changed, 380 insertions(+), 126 deletions(-) -- 1.8.3.1

[PATCH v8 0/5] KUnit-KASAN Integration

by David Gow

This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. This patchset depends on: - "kunit: extend kunit resources API" [1] - "Fix some incompatibilites between KASAN and FORTIFY_SOURCE" [2] - This is already upstream for 5.8[3,4] Changes from v7: - Rebased on top of kselftest/kunit - Rebased on top of v4 of the kunit resources API[1] - Rebased on top of v4 of the FORTIFY_SOURCE fix[2,3,4] - Updated the Kconfig entry to support KUNIT_ALL_TESTS Changes from v6: - Rebased on top of kselftest/kunit - Rebased on top of Daniel Axtens' fix for FORTIFY_SOURCE incompatibilites [2] - Removed a redundant report_enabled() check. - Fixed some places with out of date Kconfig names in the documentation. Changes from v5: - Split out the panic_on_warn changes to a separate patch. - Fix documentation to fewer to the new Kconfig names. - Fix some changes which were in the wrong patch. - Rebase on top of kselftest/kunit (currently identical to 5.7-rc1) Changes from v4: - KASAN no longer will panic on errors if both panic_on_warn and kasan_multishot are enabled. - As a result, the KASAN tests will no-longer disable panic_on_warn. - This also means panic_on_warn no-longer needs to be exported. - The use of temporary "kasan_data" variables has been cleaned up somewhat. - A potential refcount/resource leak should multiple KASAN errors appear during an assertion was fixed. - Some wording changes to the KASAN test Kconfig entries. Changes from v3: - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead. - Reordered logic in kasan_update_kunit_status() in report.c to be easier to read. - Added comment to not use the name "kasan_data" for any kunit tests outside of KUNIT_EXPECT_KASAN_FAIL(). Changes since v2: - Due to Alan's changes in [1], KUnit can be built as a module. - The name of the tests that could not be run with KUnit has been changed to be more generic: test_kasan_module. - Documentation on how to run the new KASAN tests and what to expect when running them has been added. - Some variables and functions are now static. - Now save/restore panic_on_warn in a similar way to kasan_multi_shot and renamed the init/exit functions to be more generic to accommodate. - Due to [4] in kasan_strings, kasan_memchr, and kasan_memcmp will fail if CONFIG_AMD_MEM_ENCRYPT is enabled so return early and print message explaining this circumstance. - Changed preprocessor checks to C checks where applicable. Changes since v1: - Make use of Alan Maguire's suggestion to use his patch that allows static resources for integration instead of adding a new attribute to the kunit struct - All KUNIT_EXPECT_KASAN_FAIL statements are local to each test - The definition of KUNIT_EXPECT_KASAN_FAIL is local to the test_kasan.c file since it seems this is the only place this will be used. - Integration relies on KUnit being builtin - copy_user_test has been separated into its own file since KUnit is unable to test these. This can be run as a module just as before, using CONFIG_TEST_KASAN_USER - The addition to the current task has been separated into its own patch as this is a significant enough change to be on its own.

[PATCH bpf] bpf: cgroup: allow multi-attach program to replace itself

by Lorenz Bauer

When using BPF_PROG_ATTACH to attach a program to a cgroup in BPF_F_ALLOW_MULTI mode, it is not possible to replace a program with itself. This is because the check for duplicate programs doesn't take the replacement program into account. Replacing a program with itself might seem weird, but it has some uses: first, it allows resetting the associated cgroup storage. Second, it makes the API consistent with the non-ALLOW_MULTI usage, where it is possible to replace a program with itself. Third, it aligns BPF_PROG_ATTACH with bpf_link, where replacing itself is also supported. Sice this code has been refactored a few times this change will only apply to v5.7 and later. Adjustments could be made to commit 1020c1f24a94 ("bpf: Simplify __cgroup_bpf_attach") and commit d7bf2c10af05 ("bpf: allocate cgroup storage entries on attaching bpf programs") as well as commit 324bda9e6c5a ("bpf: multi program support for cgroup+bpf") Signed-off-by: Lorenz Bauer <lmb(a)cloudflare.com> Fixes: af6eea57437a ("bpf: Implement bpf_link-based cgroup BPF program attachment") --- kernel/bpf/cgroup.c | 2 +- .../testing/selftests/bpf/prog_tests/cgroup_attach_multi.c | 7 +++++++ 2 files changed, 8 insertions(+), 1 deletion(-) diff --git a/kernel/bpf/cgroup.c b/kernel/bpf/cgroup.c index fdf7836750a3..4d76f16524cc 100644 --- a/kernel/bpf/cgroup.c +++ b/kernel/bpf/cgroup.c @@ -378,7 +378,7 @@ static struct bpf_prog_list *find_attach_entry(struct list_head *progs, } list_for_each_entry(pl, progs, node) { - if (prog && pl->prog == prog) + if (prog && pl->prog == prog && prog != replace_prog) /* disallow attaching the same prog twice */ return ERR_PTR(-EINVAL); if (link && pl->link == link) diff --git a/tools/testing/selftests/bpf/prog_tests/cgroup_attach_multi.c b/tools/testing/selftests/bpf/prog_tests/cgroup_attach_multi.c index 139f8e82c7c6..b549fcfacc0b 100644 --- a/tools/testing/selftests/bpf/prog_tests/cgroup_attach_multi.c +++ b/tools/testing/selftests/bpf/prog_tests/cgroup_attach_multi.c @@ -230,6 +230,13 @@ void test_cgroup_attach_multi(void) "prog_replace", "errno=%d\n", errno)) goto err; + /* replace program with itself */ + attach_opts.replace_prog_fd = allow_prog[6]; + if (CHECK(bpf_prog_attach_xattr(allow_prog[6], cg1, + BPF_CGROUP_INET_EGRESS, &attach_opts), + "prog_replace", "errno=%d\n", errno)) + goto err; + value = 0; CHECK_FAIL(bpf_map_update_elem(map_fd, &key, &value, 0)); CHECK_FAIL(system(PING_CMD)); -- 2.25.1

[RFC PATCH net-next 00/10] Add extended state

by Amit Cohen

Currently, drivers can only tell whether the link is up/down, but no additional information is given. This patch set provides an infrastructure that allows drivers to expose to the user more information in addition to the link state. This information can save users time which will not be wasted trying to understand why the link is not up for example. Expand the existing LINKSTATE_GET command with attributes for extended state. >From userspace, user can see the extended state like: $ ethtool ethX ...
