2021-01-16dump_common_audit_data(): fix racy accesses to ->d_nameAl Viro1-2/+5
We are not guaranteed the locking environment that would prevent dentry getting renamed right under us. And it's possible for old long name to be freed after rename, leading to UAF here. Cc: stable@kernel.org # v2.6.2+ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2021-01-16mm: don't play games with pinned pages in clear_page_refsLinus Torvalds1-0/+21
Turning a pinned page read-only breaks the pinning after COW. Don't do it. The whole "track page soft dirty" state doesn't work with pinned pages anyway, since the page might be dirtied by the pinning entity without ever being noticed in the page tables.

2021-01-16mm: fix clear_refs_write lockingLinus Torvalds1-23/+9

2021-01-15RISC-V: Fix maximum allowed phsyical memory for RV32Atish Patra1-2/+4
Linux kernel can only map 1GB of address space for RV32 as the page offset is set to 0xC0000000. The current description in the Kconfig is confusing as it indicates that RV32 can support 2GB of physical memory. That is simply not true for current kernel. In future, a 2GB split support can be added to allow 2GB physical address space.

2021-01-15RISC-V: Set current memblock limitAtish Patra1-2/+14
Currently, linux kernel can not use last 4k bytes of addressable space because IS_ERR_VALUE macro treats those as an error. This will be an issue for RV32 as any memblock allocator potentially allocate chunk of memory from the end of DRAM (2GB) leading bad address error even though the address was technically valid. Fix this issue by limiting the memblock if available memory spans the entire address space.

2021-01-15RISC-V: Do not allocate memblock while iterating reserved memblocksAtish Patra1-11/+13
Currently, resource tree allocates memory blocks while iterating on the list. It leads to following kernel warning because memblock allocation also invokes memory block reservation API.

2021-01-15io_uring: ensure finish_wait() is always called in __io_uring_task_cancel()Jens Axboe1-0/+1
If we enter with requests pending and performm cancelations, we'll have a different inflight count before and after calling prepare_to_wait(). This causes the loop to restart. If we actually ended up canceling everything, or everything completed in-between, then we'll break out of the loop without calling finish_wait() on the waitqueue. This can trigger a warning on exit_signals(), as we leave the task state in TASK_UNINTERRUPTIBLE. Put a finish_wait() after the loop to catch that case.

Once error happens latter(the error above was the ENOSPC return from ext4_add_entry in ext4_rename since all space has been consumed), the cleanup do drop the nlink for whiteout, but forget to restore 'ino' with source file.

Here we can easily include <asm/exception.h>, so let's do so. While there are a number of warnings elsewhere and some warnings enabled under W=1 are of questionable benefit, this change helps to make the code more robust as it evolved and reduces the noise somewhat, so it seems worthwhile.

2021-01-15compiler.h: Raise minimum version of GCC to 5.1 for arm64Will Deacon1-0/+6
GCC versions >= 4.9 and < 5.1 have been shown to emit memory references beyond the stack pointer, resulting in memory corruption if an interrupt is taken after the stack pointer has been adjusted but before the reference has been executed. This leads to subtle, infrequent data corruption such as the EXT4 problems reported by Russell King at the link below.

UEFI/RM no longer use IED scripts from the VBIOS, though they appear to have been updated for use by the x86 VBIOS code, so we should be able to continue using them for the moment. Unfortunately, we require some hacks to do so, as the BeforeLinkTraining IED script became a pointer to an array of scripts instead, without a revbump of the relevant tables. There's also some changes to SOR clock divider fiddling, which are hopefully correct enough that things work as they should. AFAIK, GA100 shouldn't have display, so it hasn't been added.

2021-01-14net: Allow NETIF_F_HW_TLS_TX if IP_CSUM && IPV6_CSUMTariq Toukan2-4/+10
Cited patch below blocked the TLS TX device offload unless HW_CSUM is set. This broke devices that use IP_CSUM && IP6_CSUM. Here we fix it. Note that the single HW_TLS_TX feature flag indicates support for both IPv4/6, hence it should still be disabled in case only one of (IP_CSUM | IPV6_CSUM) is set.
