FAILED: patch "[PATCH] memory: renesas-rpc-if: Avoid unaligned bus access for" failed to apply to 5.10-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.10-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 1869023e24c0de73a160a424dac4621cefd628ae Mon Sep 17 00:00:00 2001 From: Andrew Gabbasov <andrew_gabbasov(a)mentor.com> Date: Wed, 22 Sep 2021 13:48:30 -0500 Subject: [PATCH] memory: renesas-rpc-if: Avoid unaligned bus access for HyperFlash HyperFlash devices in Renesas SoCs use 2-bytes addressing, according to HW manual paragraph 62.3.3 (which officially describes Serial Flash access, but seems to be applicable to HyperFlash too). And 1-byte bus read operations to 2-bytes unaligned addresses in external address space read mode work incorrectly (returns the other byte from the same word). Function memcpy_fromio(), used by the driver to read data from the bus, in ARM64 architecture (to which Renesas cores belong) uses 8-bytes bus accesses for appropriate aligned addresses, and 1-bytes accesses for other addresses. This results in incorrect data read from HyperFlash in unaligned cases. This issue can be reproduced using something like the following commands (where mtd1 is a parition on Hyperflash storage, defined properly in a device tree): [Correct fragment, read from Hyperflash] root@rcar-gen3:~# dd if=/dev/mtd1 of=/tmp/zz bs=32 count=1 root@rcar-gen3:~# hexdump -C /tmp/zz 00000000 f4 03 00 aa f5 03 01 aa f6 03 02 aa f7 03 03 aa |................| 00000010 00 00 80 d2 40 20 18 d5 00 06 81 d2 a0 18 a6 f2 |....@ ..........| 00000020 [Incorrect read of the same fragment: see the difference at offsets 8-11] root@rcar-gen3:~# dd if=/dev/mtd1 of=/tmp/zz bs=12 count=1 root@rcar-gen3:~# hexdump -C /tmp/zz 00000000 f4 03 00 aa f5 03 01 aa 03 03 aa aa |............| 0000000c Fix this issue by creating a local replacement of the copying function, that performs only properly aligned bus accesses, and is used for reading from HyperFlash.

FAILED: patch "[PATCH] rsi: fix rate mask set leading to P2P failure" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b515d097053a71d624e0c5840b42cd4caa653941 Mon Sep 17 00:00:00 2001 From: Martin Fuzzey <martin.fuzzey(a)flowbird.group> Date: Mon, 30 Aug 2021 17:26:46 +0200 Subject: [PATCH] rsi: fix rate mask set leading to P2P failure P2P client mode was only working the first time. On subsequent connection attempts the group was successfully created but no data was sent (no transmitted data packets were seen with a sniffer). The reason for this was that the hardware was being configured in fixed rate mode with rate RSI_RATE_1 (1Mbps) which is not valid in the 5GHz band. In P2P mode wpa_supplicant uses NL80211_CMD_SET_TX_BITRATE_MASK to disallow the 11b rates in the 2.4GHz band which updated common->fixedrate_mask. rsi_set_min_rate() then used the fixedrate_mask to calculate the minimum allowed rate, or 0xffff = auto if none was found. However that calculation did not account for the different rate sets allowed in the different bands leading to the error. Fixing set_min_rate() would result in 6Mb/s being used all the time which is not what we want either. The reason the problem did not occur on the first connection is that rsi_mac80211_set_rate_mask() only updated the fixedrate_mask for the *current* band. When it was called that was still 2.4GHz as the switch is done later. So the when set_min_rate() was subsequently called after the switch to 5GHz it still had a mask of zero, leading to defaulting to auto mode. Fix this by differentiating the case of a single rate being requested, in which case the hardware will be used in fixed rate mode with just that rate, and multiple rates being requested, in which case we remain in auto mode but the firmware rate selection algorithm is configured with a restricted set of rates.

FAILED: patch "[PATCH] rsi: fix rate mask set leading to P2P failure" failed to apply to 4.4-stable tree

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b515d097053a71d624e0c5840b42cd4caa653941 Mon Sep 17 00:00:00 2001 From: Martin Fuzzey <martin.fuzzey(a)flowbird.group> Date: Mon, 30 Aug 2021 17:26:46 +0200 Subject: [PATCH] rsi: fix rate mask set leading to P2P failure P2P client mode was only working the first time. On subsequent connection attempts the group was successfully created but no data was sent (no transmitted data packets were seen with a sniffer). The reason for this was that the hardware was being configured in fixed rate mode with rate RSI_RATE_1 (1Mbps) which is not valid in the 5GHz band. In P2P mode wpa_supplicant uses NL80211_CMD_SET_TX_BITRATE_MASK to disallow the 11b rates in the 2.4GHz band which updated common->fixedrate_mask. rsi_set_min_rate() then used the fixedrate_mask to calculate the minimum allowed rate, or 0xffff = auto if none was found. However that calculation did not account for the different rate sets allowed in the different bands leading to the error. Fixing set_min_rate() would result in 6Mb/s being used all the time which is not what we want either. The reason the problem did not occur on the first connection is that rsi_mac80211_set_rate_mask() only updated the fixedrate_mask for the *current* band. When it was called that was still 2.4GHz as the switch is done later. So the when set_min_rate() was subsequently called after the switch to 5GHz it still had a mask of zero, leading to defaulting to auto mode. Fix this by differentiating the case of a single rate being requested, in which case the hardware will be used in fixed rate mode with just that rate, and multiple rates being requested, in which case we remain in auto mode but the firmware rate selection algorithm is configured with a restricted set of rates.

First of all the retry loop is not working as intended. In general the retry makes only sense if you grab the reference first and then check the sequence values. Then we should always also wait for the exclusive fence. It's also good practice to keep the reference around when installing callbacks to fences you don't own.

First of all the retry loop is not working as intended. In general the retry makes only sense if you grab the reference first and then check the sequence values. Then we should always also wait for the exclusive fence. It's also good practice to keep the reference around when installing callbacks to fences you don't own. And last the whole implementation was unnecessary complex and rather hard to understand which could lead to probably unexpected behavior of the IOCTL. Fix all this by reworking the implementation from scratch. Dropping the whole RCU approach and taking the lock instead. Only mildly tested and needs a thoughtful review of the code.

IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

FAILED: patch "[PATCH] selinux: fix race condition when computing ocontext SIDs" failed to apply to 5.4-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From cbfcd13be5cb2a07868afe67520ed181956579a7 Mon Sep 17 00:00:00 2001 From: Ondrej Mosnacek <omosnace(a)redhat.com> Date: Wed, 28 Jul 2021 16:03:13 +0200 Subject: [PATCH] selinux: fix race condition when computing ocontext SIDs Current code contains a lot of racy patterns when converting an ocontext's context structure to an SID. This is being done in a "lazy" fashion, such that the SID is looked up in the SID table only when it's first needed and then cached in the "sid" field of the ocontext structure. However, this is done without any locking or memory barriers and is thus unsafe. Between commits 24ed7fdae669 ("selinux: use separate table for initial SID lookup") and 66f8e2f03c02 ("selinux: sidtab reverse lookup hash table"), this race condition lead to an actual observable bug, because a pointer to the shared sid field was passed directly to sidtab_context_to_sid(), which was using this location to also store an intermediate value, which could have been read by other threads and interpreted as an SID. In practice this caused e.g. new mounts to get a wrong (seemingly random) filesystem context, leading to strange denials. This bug has been spotted in the wild at least twice, see [1] and [2]. Fix the race condition by making all the racy functions use a common helper that ensures the ocontext::sid accesses are made safely using the appropriate SMP constructs. Note that security_netif_sid() was populating the sid field of both contexts stored in the ocontext, but only the first one was actually used. The SELinux wiki's documentation on the "netifcon" policy statement [3] suggests that using only the first context is intentional. I kept only the handling of the first context here, as there is really no point in doing the SID lookup for the unused one. I wasn't able to reproduce the bug mentioned above on any kernel that includes commit 66f8e2f03c02, even though it has been reported that the issue occurs with that commit, too, just less frequently. Thus, I wasn't able to verify that this patch fixes the issue, but it makes sense to avoid the race condition regardless.

FAILED: patch "[PATCH] selinux: fix race condition when computing ocontext SIDs" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From cbfcd13be5cb2a07868afe67520ed181956579a7 Mon Sep 17 00:00:00 2001 From: Ondrej Mosnacek <omosnace(a)redhat.com> Date: Wed, 28 Jul 2021 16:03:13 +0200 Subject: [PATCH] selinux: fix race condition when computing ocontext SIDs Current code contains a lot of racy patterns when converting an ocontext's context structure to an SID. This is being done in a "lazy" fashion, such that the SID is looked up in the SID table only when it's first needed and then cached in the "sid" field of the ocontext structure. However, this is done without any locking or memory barriers and is thus unsafe. Between commits 24ed7fdae669 ("selinux: use separate table for initial SID lookup") and 66f8e2f03c02 ("selinux: sidtab reverse lookup hash table"), this race condition lead to an actual observable bug, because a pointer to the shared sid field was passed directly to sidtab_context_to_sid(), which was using this location to also store an intermediate value, which could have been read by other threads and interpreted as an SID. In practice this caused e.g. new mounts to get a wrong (seemingly random) filesystem context, leading to strange denials. This bug has been spotted in the wild at least twice, see [1] and [2]. Fix the race condition by making all the racy functions use a common helper that ensures the ocontext::sid accesses are made safely using the appropriate SMP constructs. Note that security_netif_sid() was populating the sid field of both contexts stored in the ocontext, but only the first one was actually used. The SELinux wiki's documentation on the "netifcon" policy statement [3] suggests that using only the first context is intentional. I kept only the handling of the first context here, as there is really no point in doing the SID lookup for the unused one. I wasn't able to reproduce the bug mentioned above on any kernel that includes commit 66f8e2f03c02, even though it has been reported that the issue occurs with that commit, too, just less frequently. Thus, I wasn't able to verify that this patch fixes the issue, but it makes sense to avoid the race condition regardless.

This is being done in a "lazy" fashion, such that the SID is looked up in the SID table only when it's first needed and then cached in the "sid" field of the ocontext structure. However, this is done without any locking or memory barriers and is thus unsafe. Between commits 24ed7fdae669 ("selinux: use separate table for initial SID lookup") and 66f8e2f03c02 ("selinux: sidtab reverse lookup hash table"), this race condition lead to an actual observable bug, because a pointer to the shared sid field was passed directly to sidtab_context_to_sid(), which was using this location to also store an intermediate value, which could have been read by other threads and interpreted as an SID. In practice this caused e.g. new mounts to get a wrong (seemingly random) filesystem context, leading to strange denials. This bug has been spotted in the wild at least twice, see [1] and [2]. Fix the race condition by making all the racy functions use a common helper that ensures the ocontext::sid accesses are made safely using the appropriate SMP constructs. Note that security_netif_sid() was populating the sid field of both contexts stored in the ocontext, but only the first one was actually used. The SELinux wiki's documentation on the "netifcon" policy statement [3] suggests that using only the first context is intentional. I kept only the handling of the first context here, as there is really no point in doing the SID lookup for the unused one. I wasn't able to reproduce the bug mentioned above on any kernel that includes commit 66f8e2f03c02, even though it has been reported that the issue occurs with that commit, too, just less frequently. Thus, I wasn't able to verify that this patch fixes the issue, but it makes sense to avoid the race condition regardless.

FAILED: patch "[PATCH] btrfs: fix deadlock between chunk allocation and chunk btree" failed to apply to 5.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 5.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 2bb2e00ed9787e52580bb651264b8d6a2b7a9dd2 Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Wed, 13 Oct 2021 10:12:49 +0100 Subject: [PATCH] btrfs: fix deadlock between chunk allocation and chunk btree modifications When a task is doing some modification to the chunk btree and it is not in the context of a chunk allocation or a chunk removal, it can deadlock with another task that is currently allocating a new data or metadata chunk. These contexts are the following: * When relocating a system chunk, when we need to COW the extent buffers that belong to the chunk btree; * When adding a new device (ioctl), where we need to add a new device item to the chunk btree; * When removing a device (ioctl), where we need to remove a device item from the chunk btree; * When resizing a device (ioctl), where we need to update a device item in the chunk btree and may need to relocate a system chunk that lies beyond the new device size when shrinking a device. The problem happens due to a sequence of steps like the following: 1) Task A starts a data or metadata chunk allocation and it locks the chunk mutex; 2) Task B is relocating a system chunk, and when it needs to COW an extent buffer of the chunk btree, it has locked both that extent buffer as well as its parent extent buffer; 3) Since there is not enough available system space, either because none of the existing system block groups have enough free space or because the only one with enough free space is in RO mode due to the relocation, task B triggers a new system chunk allocation. It blocks when trying to acquire the chunk mutex, currently held by task A; 4) Task A enters btrfs_chunk_alloc_add_chunk_item(), in order to insert the new chunk item into the chunk btree and update the existing device items there. But in order to do that, it has to lock the extent buffer that task B locked at step 2, or its parent extent buffer, but task B is waiting on the chunk mutex, which is currently locked by task A, therefore resulting in a deadlock. One example report when the deadlock happens with system chunk relocation: INFO: task kworker/u9:5:546 blocked for more than 143 seconds.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 2bb2e00ed9787e52580bb651264b8d6a2b7a9dd2 Mon Sep 17 00:00:00 2001 From: Filipe Manana <fdmanana(a)suse.com> Date: Wed, 13 Oct 2021 10:12:49 +0100 Subject: [PATCH] btrfs: fix deadlock between chunk allocation and chunk btree modifications When a task is doing some modification to the chunk btree and it is not in the context of a chunk allocation or a chunk removal, it can deadlock with another task that is currently allocating a new data or metadata chunk. These contexts are the following: * When relocating a system chunk, when we need to COW the extent buffers that belong to the chunk btree; * When adding a new device (ioctl), where we need to add a new device item to the chunk btree; * When removing a device (ioctl), where we need to remove a device item from the chunk btree; * When resizing a device (ioctl), where we need to update a device item in the chunk btree and may need to relocate a system chunk that lies beyond the new device size when shrinking a device. The problem happens due to a sequence of steps like the following: 1) Task A starts a data or metadata chunk allocation and it locks the chunk mutex; 2) Task B is relocating a system chunk, and when it needs to COW an extent buffer of the chunk btree, it has locked both that extent buffer as well as its parent extent buffer; 3) Since there is not enough available system space, either because none of the existing system block groups have enough free space or because the only one with enough free space is in RO mode due to the relocation, task B triggers a new system chunk allocation. It blocks when trying to acquire the chunk mutex, currently held by task A; 4) Task A enters btrfs_chunk_alloc_add_chunk_item(), in order to insert the new chunk item into the chunk btree and update the existing device items there. But in order to do that, it has to lock the extent buffer that task B locked at step 2, or its parent extent buffer, but task B is waiting on the chunk mutex, which is currently locked by task A, therefore resulting in a deadlock. One example report when the deadlock happens with system chunk relocation: INFO: task kworker/u9:5:546 blocked for more than 143 seconds.

FAILED: patch "[PATCH] x86/iopl: Fake iopl(3) CLI/STI usage" failed to apply to 5.10-stable tree

The patch below does not apply to the 5.10-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From b968e84b509da593c50dc3db679e1d33de701f78 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra <peterz(a)infradead.org> Date: Fri, 17 Sep 2021 11:20:04 +0200 Subject: [PATCH] x86/iopl: Fake iopl(3) CLI/STI usage Since commit c8137ace5638 ("x86/iopl: Restrict iopl() permission scope") it's possible to emulate iopl(3) using ioperm(), except for the CLI/STI usage. Userspace CLI/STI usage is very dubious (read broken), since any exception taken during that window can lead to rescheduling anyway (or worse). The IOPL(2) manpage even states that usage of CLI/STI is highly discouraged and might even crash the system. Of course, that won't stop people and HP has the dubious honour of being the first vendor to be found using this in their hp-health package. In order to enable this 'software' to still 'work', have the #GP treat the CLI/STI instructions as NOPs when iopl(3). Warn the user that their program is doing dubious things.

To be specific, the case which goes wrong is: 1. Zen1 (or earlier) and Zen2 (or later) in a migration pool 2. Linux boots on Zen2, probes and finds the absence of X86_BUG_NULL_SEL 3. Linux is then migrated to Zen1 Linux is now running on a X86_BUG_NULL_SEL-impacted CPU while believing that the bug is fixed. The only way to address the problem is to fully trust the "no longer affected" CPUID bit when virtualised, because in the above case it would be clear deliberately to indicate the fact "you might migrate to somewhere which has this behaviour". Zen3 adds the NullSelectorClearsBase CPUID bit to indicate that loading a NULL segment selector zeroes the base and limit fields, as well as just attributes. Zen2 also has this behaviour but doesn't have the NSCB bit.

Although the addition and deletion of those slots are protected by mixer->reg_mutex, the access to slots aren't, hence this may cause UAF when the slots in use are deleted concurrently. This patch applies the mixer->reg_mutex in all appropriate code paths (i.e. the ioctl functions) that may access slots.

[PATCH] tty: serial: msm_serial: Deactivate RX DMA for polling support

by Sven Eckelmann

The CONSOLE_POLLING mode is used for tools like k(g)db. In this kind of setup, it is often sharing a serial device with the normal system console. This is usually no problem because the polling helpers can consume input values directly (when in kgdb context) and the normal Linux handlers can only consume new input values after kgdb switched back. This is not true anymore when RX DMA is enabled for UARTDM controllers. Single input values can no longer be received correctly. Instead following seems to happen: * on 1. input, some old input is read (continuously) * on 2. input, two old inputs are read (continuously) * on 3. input, three old input values are read (continuously) * on 4. input, 4 previous inputs are received This repeats then for each group of 4 input values. This behavior changes slightly depending on what state the controller was when the first input was received. But this makes working with kgdb basically impossible because control messages are always corrupted when kgdboc tries to parse them. RX DMA should therefore be off when CONSOLE_POLLING is enabled to avoid these kind of problems. No such problem was noticed for TX DMA.

FAILED: patch "[PATCH] scsi: core: Avoid leaving shost->last_reset with stale value" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree.

Milne" <emilne(a)redhat.com> Date: Fri, 29 Oct 2021 15:43:10 -0400 Subject: [PATCH] scsi: core: Avoid leaving shost->last_reset with stale value if EH does not run The changes to issue the abort from the scmd->abort_work instead of the EH thread introduced a problem if eh_deadline is used. If aborting the command(s) is successful, and there are never any scmds added to the shost->eh_cmd_q, there is no code path which will reset the ->last_reset value back to zero. The effect of this is that after a successful abort with no EH thread activity, a subsequent timeout, perhaps a long time later, might immediately be considered past a user-set eh_deadline time, and the host will be reset with no attempt at recovery. Fix this by resetting ->last_reset back to zero in scmd_eh_abort_handler() if it is determined that the EH thread will not run to do this. Thanks to Gopinath Marappan for investigating this problem.
