bpf: Enlarge offset check value to INT_MAX in bpf_skb_{load,store}_bytes

2022-06-06T06:42:45+00:00

commit 45969b4152c1752089351cd6836a42a566d49bcf upstream. The data length of skb frags + frag_list may be greater than 0xffff, and skb_header_pointer can not handle negative offset. So, here INT_MAX is used to check the validity of offset. Add the same change to the related function skb_store_bytes.

bpf: Fix potential array overflow in bpf_trampoline_get_progs()

2022-06-06T06:42:45+00:00

commit a2aa95b71c9bbec793b5c5fa50f0a80d882b3e8d upstream. The cnt value in the 'cnt >= BPF_MAX_TRAMP_PROGS' check does not include BPF_TRAMP_MODIFY_RETURN bpf programs, so the number of the attached BPF_TRAMP_MODIFY_RETURN bpf programs in a trampoline can exceed BPF_MAX_TRAMP_PROGS. When this happens, the assignment '*progs++ = aux->prog' in bpf_trampoline_get_progs() will cause progs array overflow as the progs field in the bpf_tramp_progs struct can only hold at most BPF_MAX_TRAMP_PROGS bpf programs.

NFSD: Fix possible sleep during nfsd4_release_lockowner()

2022-06-06T06:42:45+00:00

commit ce3c4ad7f4ce5db7b4f08a1e237d8dd94b39180b upstream. nfsd4_release_lockowner() holds clp->cl_lock when it calls check_for_locks(). However, check_for_locks() calls nfsd_file_get() / nfsd_file_put() to access the backing inode's flc_posix list, and nfsd_file_put() can sleep if the inode was recently removed. Let's instead rely on the stateowner's reference count to gate whether the release is permitted. This should be a reliable indication of locks-in-use since file lock operations and ->lm_get_owner take appropriate references, which are released appropriately when file locks are removed.

NFS: Memory allocation failures are not server fatal errors

commit 452284407c18d8a522c3039339b1860afa0025a8 upstream. We need to filter out ENOMEM in nfs_error_is_fatal_on_server(), because running out of memory on our client is not a server error.

docs: submitting-patches: Fix crossref to 'The canonical patch format'

2022-06-06T06:42:44+00:00

commit 6d5aa418b3bd42cdccc36e94ee199af423ef7c84 upstream. The reference to `explicit_in_reply_to` is pointless as when the reference was added in the form of "#15" [1], Section 15) was "The canonical patch format". The reference of "#15" had not been properly updated in a couple of reorganizations during the plain-text SubmittingPatches era. Fix it by using `the_canonical_patch_format`.

tpm: Fix buffer access in tpm2_get_tpm_pt()

commit e57b2523bd37e6434f4e64c7a685e3715ad21e9a upstream. Under certain conditions uninitialized memory will be accessed. As described by TCG Trusted Platform Module Library Specification, rev. 1.59 (Part 3: Commands), if a TPM2_GetCapability is received, requesting a capability, the TPM in field upgrade mode may return a zero length list.

HID: multitouch: add quirks to enable Lenovo X12 trackpoint

commit 95cd2cdc88c755dcd0a58b951faeb77742c733a4 upstream. This applies the similar quirks used by previous generation devices such as X1 tablet for X12 tablet, so that the trackpoint and buttons can work.
