Revert "staging: rtl8192e: Replace macro RTL_PCI_DEVICE with PCI_DEVICE"

2023-06-14T09:15:34Z

This reverts commit ec310591cf839653a5b2c1fcf6b8a110c3f2485c which is commit fda2093860df4812d69052a8cf4997e53853a340 upstream. Ben reports that this should not have been backported to the older kernels as the rest of the macro is not empty. It was a clean-up patch in 6.4-rc1 only, it did not add new device ids.

wifi: rtw88: correct PS calculation for SUPPORTS_DYNAMIC_PS

2023-06-14T09:15:34Z

commit 3918dd0177ee08970683a2c22a3388825d82fd79 upstream. This driver relies on IEEE80211_CONF_PS of hw->conf.flags to turn off PS or turn on dynamic PS controlled by driver and firmware. Though this would be incorrect, it did work before because the flag is always recalculated until the commit 28977e790b5d ("wifi: mac80211: skip powersave recalc if driver SUPPORTS_DYNAMIC_PS") is introduced by kernel 5.20 to skip to recalculate IEEE80211_CONF_PS of hw->conf.flags if driver sets SUPPORTS_DYNAMIC_PS. Correct this by doing recalculation while BSS_CHANGED_PS is changed and interface is added or removed. It is allowed to enter PS only if single one station vif is working. Without this fix, driver doesn't enter PS anymore that causes higher power consumption.

wifi: rtw89: correct PS calculation for SUPPORTS_DYNAMIC_PS

Correct this by doing recalculation while BSS_CHANGED_PS is changed and interface is added or removed. For now, it is allowed to enter PS only if single one station vif is working, and it could possible to have PS per vif after firmware can support it.

ext4: only check dquot_initialize_needed() when debugging

2023-06-14T09:15:33Z

commit dea9d8f7643fab07bf89a1155f1f94f37d096a5e upstream. ext4_xattr_block_set() relies on its caller to call dquot_initialize() on the inode. To assure that this has happened there are WARN_ON checks. Unfortunately, this is subject to false positives if there is an antagonist thread which is flipping the file system at high rates between r/o and rw. So only do the check if EXT4_XATTR_DEBUG is enabled. Link: https://lore.kernel.org/r/20230608044056.GA1418535@mit.edu Signed-off-by: Theodore Ts'o Signed-off-by: Greg Kroah-Hartman

ksmbd: check the validation of pdu_size in ksmbd_conn_handler_loop

2023-06-14T09:15:33Z

commit 368ba06881c395f1c9a7ba22203cf8d78b4addc0 upstream. The length field of netbios header must be greater than the SMB header sizes(smb1 or smb2 header), otherwise the packet is an invalid SMB packet. If `pdu_size` is 0, ksmbd allocates a 4 bytes chunk to `conn->request_buf`. In the function `get_smb2_cmd_val` ksmbd will read cmd from `rcv_hdr->Command`, which is `conn->request_buf + 12`, causing the KASAN detector to print the following error message: [ 7.205018] BUG: KASAN: slab-out-of-bounds in get_smb2_cmd_val+0x45/0x60 [ 7.205423] Read of size 2 at addr ffff8880062d8b50 by task ksmbd:42632/248 ...

ksmbd: fix out-of-bound read in parse_lease_state()

2023-06-14T09:15:33Z

commit fc6c6a3c324c1b3e93a03d0cfa3749c781f23de0 upstream. This bug is in parse_lease_state, and it is caused by the missing check of `struct create_context`. When the ksmbd traverses the create_contexts, it doesn't check if the field of `NameOffset` and `Next` is valid, The KASAN message is following: [ 6.664323] BUG: KASAN: slab-out-of-bounds in parse_lease_state+0x7d/0x280 [ 6.664738] Read of size 2 at addr ffff888005c08988 by task kworker/0:3/103 ...

ksmbd: fix out-of-bound read in deassemble_neg_contexts()

2023-06-14T09:15:33Z

commit f1a411873c85b642f13b01f21b534c2bab81fc1b upstream. The check in the beginning is `clen + sizeof(struct smb2_neg_context) <= len_of_ctxts`, but in the end of loop, `len_of_ctxts` will subtract `((clen + 7) & ~0x7) + sizeof(struct smb2_neg_context)`, which causes integer underflow when clen does the 8 alignment. We should use `(clen + 7) & ~0x7` in the check to avoid underflow from happening. Then there are some variables that need to be declared unsigned instead of signed.
