2022-08-08vfs: Check the truncate maximum size in inode_newsize_ok()David Howells1-0/+2
If something manages to set the maximum file size to MAX_OFFSET+1, this can cause the xfs and ext4 filesystems at least to become corrupt. Ordinarily, the kernel protects against userspace trying this by checking the value early in the truncate() and ftruncate() system calls calls - but there are at least two places that this check is bypassed: (1) Cachefiles will round up the EOF of the backing file to DIO block size so as to allow DIO on the final block - but this might push the offset negative. It then calls notify_change(), but this inadvertently bypasses the checking. This can be triggered if someone puts an 8EiB-1 file on a server for someone else to try and access by, say, nfs. (2) ksmbd doesn't check the value it is given in set_end_of_file_info() and then calls vfs_truncate() directly - which also bypasses the check. In both cases, it is potentially possible for a network filesystem to cause a disk filesystem to be corrupted: cachefiles in the client's cache filesystem; ksmbd in the server's filesystem. nfsd is okay as it checks the value, but we can then remove this check too. Fix this by adding a check to inode_newsize_ok(), as called from setattr_prepare(), thereby catching the issue as filesystems set up to perform the truncate with minimal opportunity for bypassing the new check.

2022-08-08drm/i915/gt: Skip TLB invalidations once wedgedChris Wilson1-0/+3
Skip all further TLB invalidations once the device is wedged and had been reset, as, on such cases, it can no longer process instructions on the GPU and the user no longer has access to the TLB's in each engine. So, an attempt to do a TLB cache invalidation will produce a timeout. That helps to reduce the performance regression introduced by TLB invalidate logic.

2022-08-08wifi: cfg80211: Fix validating BSS pointers in __cfg80211_connect_resultVeerendranath Jakkam1-3/+5
Driver's SME is allowed to fill either BSSID or BSS pointers in struct cfg80211_connect_resp_params when indicating connect response but a check in __cfg80211_connect_result() is giving unnecessary warning when driver's SME fills only BSSID pointer and not BSS pointer in struct cfg80211_connect_resp_params. In case of mac80211 with auth/assoc path, it is always expected to fill BSS pointers in struct cfg80211_connect_resp_params when calling __cfg80211_connect_result() since cfg80211 must have hold BSS pointers in cfg80211_mlme_assoc(). So, skip the check for the drivers which support cfg80211 connect callback, for example with brcmfmac is one such driver which had the warning: WARNING: CPU: 5 PID: 514 at net/wireless/sme.c:786 __cfg80211_connect_result+0x2fc/0x5c0 [cfg80211] Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Fixes: efbabc116500 ("cfg80211: Indicate MLO connection info in connect and roam callbacks") Signed-off-by: Veerendranath Jakkam <quic_vjakkam@quicinc.com> [kvalo@kernel.org: add more info to the commit log] Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20220805135259.4126630-1-quic_vjakkam@quicinc.com
