2022-04-28net: phy: Deduplicate interrupt disablement on PHY attachLukas Wunner1-4/+2
phy_attach_direct() first calls phy_init_hw() (which restores interrupt settings through ->config_intr()), then calls phy_disable_interrupts(). So if phydev->interrupts was previously set to 1, interrupts are briefly enabled, then disabled, which seems nonsensical. If it was previously set to 0, interrupts are disabled twice, which is equally nonsensical. Deduplicate interrupt disablement.

2022-04-28net: enetc: allow tc-etf offload even with NETIF_F_CSUM_MASKVladimir Oltean1-4/+0
The Time-Specified Departure feature is indeed mutually exclusive with TX IP checksumming in ENETC, but TX checksumming in itself is broken and was removed from this driver in commit 82728b91f124 ("enetc: Remove Tx checksumming offload code"). The blamed commit declared NETIF_F_HW_CSUM in dev->features to comply with software TSO's expectations, and still did the checksumming in software by calling skb_checksum_help(). So there isn't any restriction for the Time-Specified Departure feature. However, enetc_setup_tc_txtime() doesn't understand that, and blindly looks for NETIF_F_CSUM_MASK. Instead of checking for things which can literally never happen in the current code base, just remove the check and let the driver offload tc-etf qdiscs.

Commit 00bfe02f4796 ("gfs2: Fix mmap + page fault deadlocks for buffered I/O") changed gfs2_file_read_iter() and gfs2_file_buffered_write() to allow dropping the inode glock while faulting in user buffers. When the lock was dropped, a short result was returned to indicate that the operation was interrupted. As pointed out by Linus (see the link below), this behavior is broken and the operations should always re-acquire the inode glock and resume the operation instead.

2022-04-27tls: Skip tls_append_frag on zero copy sizeMaxim Mikityanskiy1-5/+7
Calling tls_append_frag when max_open_record_len == record->len might add an empty fragment to the TLS record if the call happens to be on the page boundary. Normally tls_append_frag coalesces the zero-sized fragment to the previous one, but not if it's on page boundary. If a resync happens then, the mlx5 driver posts dump WQEs in tx_post_resync_dump, and the empty fragment may become a data segment with byte_count == 0, which will confuse the NIC and lead to a CQE error. This commit fixes the described issue by skipping tls_append_frag on zero size to avoid adding empty fragments. The fix is not in the driver, because an empty fragment is hardly the desired behavior.

occur at same time kasan_quarantine_remove_cache() is called in kmem_cache_shrink()/ destroy(). The kasan_quarantine_remove_cache() call is protected by cpuslock in kmem_cache_destroy() to ensure serialization with kasan_cpu_offline(). However the kasan_quarantine_remove_cache() call is not protected by cpuslock in kmem_cache_shrink(). When a CPU is going offline and cache shrink occurs at same time, the cpu_quarantine may be corrupted by interrupt (per_cpu_remove_cache operation). So add a cpu_quarantine offline flags check in per_cpu_remove_cache().

2022-04-27intel_idle: Fix SPR C6 optimizationArtem Bityutskiy1-5/+3
The Sapphire Rapids (SPR) C6 optimization was added to the end of the 'spr_idle_state_table_update()' function. However, the function has a 'return' which may happen before the optimization has a chance to run. And this may prevent the optimization from happening. This is an unlikely scenario, but possible if user boots with, say, the 'intel_idle.preferred_cstates=6' kernel boot option. This patch fixes the issue by eliminating the problematic 'return' statement.

2022-04-27intel_idle: Fix the 'preferred_cstates' module parameterArtem Bityutskiy1-7/+12
Problem description. When user boots kernel up with the 'intel_idle.preferred_cstates=4' option, we enable C1E and disable C1 states on Sapphire Rapids Xeon (SPR). In order for C1E to work on SPR, we have to enable the C1E promotion bit on all CPUs. However, we enable it only on one CPU. Fix description. The 'intel_idle' driver already has the infrastructure for disabling C1E promotion on every CPU. This patch uses the same infrastructure for enabling C1E promotion on every CPU. It changes the boolean 'disable_promotion_to_c1e' variable to a tri-state 'c1e_promotion' variable. Tested on a 2-socket SPR system. I verified the following combinations: * C1E promotion enabled and disabled in BIOS. * Booted with and without the 'intel_idle.preferred_cstates=4' kernel argument. In all 4 cases C1E promotion was correctly set on all CPUs. Also tested on an old Broadwell system, just to make sure it does not cause a regression. C1E promotion was correctly disabled on that system, both C1 and C1E were exposed (as expected).

2022-04-27hex2bin: fix access beyond string endMikulas Patocka1-3/+6
If we pass too short string to "hex2bin" (and the string size without the terminating NUL character is even), "hex2bin" reads one byte after the terminating NUL character. This patch fixes it. Note that hex_to_bin returns -1 on error and hex2bin return -EINVAL on error - so we can't just return the variable "hi" or "lo" on error. This inconsistency may be fixed in the next merge window, but for the purpose of fixing this bug, we just preserve the existing behavior and return -1 and -EINVAL.

2022-04-27hex2bin: make the function hex_to_bin constant-timeMikulas Patocka2-8/+26
The function hex2bin is used to load cryptographic keys into device mapper targets dm-crypt and dm-integrity. It should take constant time independent on the processed data, so that concurrently running unprivileged code can't infer any information about the keys via microarchitectural convert channels. This patch changes the function hex_to_bin so that it contains no branches and no memory accesses. Note that this shouldn't cause performance degradation because the size of the new function is the same as the size of the old function (on x86-64) - and the new function causes no branch misprediction penalties. I compile-tested this function with gcc on aarch64 alpha arm hppa hppa64 i386 ia64 m68k mips32 mips64 powerpc powerpc64 riscv sh4 s390x sparc32 sparc64 x86_64 and with clang on aarch64 arm hexagon i386 mips32 mips64 powerpc powerpc64 s390x sparc32 sparc64 x86_64 to verify that there are no branches in the generated code.

2022-04-27floppy: disable FDRAWCMD by defaultWilly Tarreau2-11/+48
Minh Yuan reported a concurrency use-after-free issue in the floppy code between raw_cmd_ioctl and seek_interrupt. [ It turns out this has been around, and that others have reported the KASAN splats over the years, but Minh Yuan had a reproducer for it and so gets primary credit for reporting it for this fix - Linus ] The problem is, this driver tends to break very easily and nowadays, nobody is expected to use FDRAWCMD anyway since it was used to manipulate non-standard formats. The risk of breaking the driver is higher than the risk presented by this race, and accessing the device requires privileges anyway. Let's just add a config option to completely disable this ioctl and leave it disabled by default. Distros shouldn't use it, and only those running on antique hardware might need to enable it.

2022-04-27platform/x86/intel: pmc/core: change pmc_lpm_modes to staticTom Rix1-1/+1
Sparse reports this issue core.c: note: in included file: core.h:239:12: warning: symbol 'pmc_lpm_modes' was not declared. Should it be static? Global variables should not be defined in headers. This only works because core.h is only included by core.c. Single file use variables should be static, so change its storage-class specifier to static.

Due to change in firmware flow, update mailbox writes to poll on ready bit instead of run_busy bit.

To prevent an agent from indefinitely holding the mailbox firmware has implemented a leaky bucket algorithm. Repeated access to the mailbox may now incur a delay of up to 2.1 seconds.
