2022-07-25intel_idle: Fix false positive RCU splats due to incorrect hardirqs stateWaiman Long1-1/+7
Commit 32d4fd5751ea ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE") uses raw_local_irq_enable/local_irq_disable() around call to __intel_idle() in intel_idle_irq(). With interrupt enabled, timer tick interrupt can happen and a subsequently call to __do_softirq() may change the lockdep hardirqs state of a debug kernel back to 'on'. This will result in a mismatch between the cpu hardirqs state (off) and the lockdep hardirqs state (on) causing a number of false positive "WARNING: suspicious RCU usage" splats. Fix that by using local_irq_disable() to disable interrupt in intel_idle_irq().

2022-07-25drm/i915/reset: Add additional steps for Wa_22011802037 for execlist backendUmesh Nerlige Ramappa5-79/+103
For execlists backend, current implementation of Wa_22011802037 is to stop the CS before doing a reset of the engine. This WA was further extended to wait for any pending MI FORCE WAKEUPs before issuing a reset. Add the extended steps in the execlist path of reset. In addition, extend the WA to gen11. v2: (Tvrtko) - Clarify comments, commit message, fix typos - Use IS_GRAPHICS_VER for gen 11/12 checks v3: (Daneile) - Drop changes to intel_ring_submission since WA does not apply to it - Log an error if MSG IDLE is not defined for an engine Signed-off-by: Umesh Nerlige Ramappa <[email protected]> Fixes: f6aa0d713c88 ("drm/i915: Add Wa_22011802037 force cs halt") Acked-by: Tvrtko Ursulin <[email protected]> Reviewed-by: Daniele Ceraolo Spurio <[email protected]> Signed-off-by: John Harrison <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 0667429ce68e0b08f9f1fec8fd0b1f57228f605e) Signed-off-by: Tvrtko Ursulin <[email protected]>

2022-07-25net: macsec: fix potential resource leak in macsec_add_rxsa() and ↵Jianglei Nie1-2/+2
macsec_add_txsa() init_rx_sa() allocates relevant resource for rx_sa->stats and rx_sa-> key.tfm with alloc_percpu() and macsec_alloc_tfm(). When some error occurs after init_rx_sa() is called in macsec_add_rxsa(), the function released rx_sa with kfree() without releasing rx_sa->stats and rx_sa-> key.tfm, which will lead to a resource leak. We should call macsec_rxsa_put() instead of kfree() to decrease the ref count of rx_sa and release the relevant resource if the refcount is 0. The same bug exists in macsec_add_txsa() for tx_sa as well. This patch fixes the above two bugs.

2022-07-25macsec: always read MACSEC_SA_ATTR_PN as a u64Sabrina Dubroca1-3/+3
Currently, MACSEC_SA_ATTR_PN is handled inconsistently, sometimes as a u32, sometimes forced into a u64 without checking the actual length of the attribute. Instead, we can use nla_get_u64 everywhere, which will read up to 64 bits into a u64, capped by the actual length of the attribute coming from userspace. This fixes several issues: - the check in validate_add_rxsa doesn't work with 32-bit attributes - the checks in validate_add_txsa and validate_upd_sa incorrectly reject X << 32 (with X != 0) Fixes: 48ef50fa866a ("macsec: Netlink support of XPN cipher suites (IEEE 802.1AEbw)") Signed-off-by: Sabrina Dubroca <[email protected]> Signed-off-by: David S.

2022-07-25macsec: limit replay window size with XPNSabrina Dubroca1-4/+12
IEEE 802.1AEbw-2013 (section 10.7.8) specifies that the maximum value of the replay window is 2^30-1, to help with recovery of the upper bits of the PN. To avoid leaving the existing macsec device in an inconsistent state if this test fails during changelink, reuse the cleanup mechanism introduced for HW offload. This wasn't needed until now because macsec_changelink_common could not fail during changelink, as modifying the cipher suite was not allowed. Finally, this must happen after handling IFLA_MACSEC_CIPHER_SUITE so that secy->xpn is set.

Commit 48ef50fa866a added a test on tb_sa[MACSEC_SA_ATTR_PN], but nothing guarantees that it's not NULL at this point. The same code was added to macsec_add_txsa, but there it's not a problem because validate_add_txsa checks that the MACSEC_SA_ATTR_PN attribute is present. Note: it's not possible to reproduce with iproute, because iproute doesn't allow creating an SA without specifying the PN.

2022-07-25arm64: Delay initialisation of cpuinfo_arm64::reg_{zcr,smcr}Marc Zyngier2-28/+29
Even if we are now able to tell the kernel to avoid exposing SVE/SME from the command line, we still have a couple of places where we unconditionally access the ZCR_EL1 (resp. SMCR_EL1) registers. On systems with broken firmwares, this results in a crash even if arm64.nosve (resp. arm64.nosme) was passed on the command-line. To avoid this, only update cpuinfo_arm64::reg_{zcr,smcr} once we have computed the sanitised version for the corresponding feature registers (ID_AA64PFR0 for SVE, and ID_AA64PFR1 for SME). This results in some minor refactoring.

arch/x86/Kbuild guards the entire purgatory/ directory, and CONFIG_KEXEC_FILE is bool type. $(CONFIG_KEXEC_FILE) is always 'y' when this directory is being built.

2022-07-24Documentation: fix sctp_wmem in ip-sysctl.rstXin Long1-1/+8
Since commit 1033990ac5b2 ("sctp: implement memory accounting on tx path"), SCTP has supported memory accounting on tx path where 'sctp_wmem' is used by sk_wmem_schedule(). So we should fix the description for this option in ip-sysctl.rst accordingly. v1->v2: - Improve the description as Marcelo suggested.

2022-07-24net/tls: Remove the context from the list in tls_device_downMaxim Mikityanskiy1-1/+6
tls_device_down takes a reference on all contexts it's going to move to the degraded state (software fallback). If sk_destruct runs afterwards, it can reduce the reference counter back to 1 and return early without destroying the context. Then tls_device_down will release the reference it took and call tls_device_free_ctx. However, the context will still stay in tls_device_down_list forever. The list will contain an item, memory for which is released, making a memory corruption possible. Fix the above bug by properly removing the context from all lists before any call to tls_device_free_ctx.
