Title
libie: don't unroll if fwlog isn't supported
Summary
In the Linux kernel, the following vulnerability has been resolved: libie: don't unroll if fwlog isn't supported The libie_fwlog_deinit() function can be called during driver unload even when firmware logging was never properly initialized. This led to call trace: [ 148.576156] Oops: Oops: 0000 [#1] SMP NOPTI [ 148.576167] CPU: 80 UID: 0 PID: 12843 Comm: rmmod Kdump: loaded Not tainted 6.17.0-rc7next-queue-3oct-01915-g06d79d51cf51 #1 PREEMPT(full) [ 148.576177] Hardware name: HPE ProLiant DL385 Gen10 Plus/ProLiant DL385 Gen10 Plus, BIOS A42 07/18/2020 [ 148.576182] RIP: 0010:__dev_printk+0x16/0x70 [ 148.576196] Code: 1f 44 00 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 00 00 41 55 41 54 49 89 d4 55 48 89 fd 53 48 85 f6 74 3c <4c> 8b 6e 50 48 89 f3 4d 85 ed 75 03 4c 8b 2e 48 89 df e8 f3 27 98 [ 148.576204] RSP: 0018:ffffd2fd7ea17a48 EFLAGS: 00010202 [ 148.576211] RAX: ffffd2fd7ea17aa0 RBX: ffff8eb288ae2000 RCX: 0000000000000000 [ 148.576217] RDX: ffffd2fd7ea17a70 RSI: 00000000000000c8 RDI: ffffffffb68d3d88 [ 148.576222] RBP: ffffffffb68d3d88 R08: 0000000000000000 R09: 0000000000000000 [ 148.576227] R10: 00000000000000c8 R11: ffff8eb2b1a49400 R12: ffffd2fd7ea17a70 [ 148.576231] R13: ffff8eb3141fb000 R14: ffffffffc1215b48 R15: ffffffffc1215bd8 [ 148.576236] FS: 00007f5666ba6740(0000) GS:ffff8eb2472b9000(0000) knlGS:0000000000000000 [ 148.576242] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 148.576247] CR2: 0000000000000118 CR3: 000000011ad17000 CR4: 0000000000350ef0 [ 148.576252] Call Trace: [ 148.576258] <TASK> [ 148.576269] _dev_warn+0x7c/0x96 [ 148.576290] libie_fwlog_deinit+0x112/0x117 [libie_fwlog] [ 148.576303] ixgbe_remove+0x63/0x290 [ixgbe] [ 148.576342] pci_device_remove+0x42/0xb0 [ 148.576354] device_release_driver_internal+0x19c/0x200 [ 148.576365] driver_detach+0x48/0x90 [ 148.576372] bus_remove_driver+0x6d/0xf0 [ 148.576383] pci_unregister_driver+0x2e/0xb0 [ 148.576393] ixgbe_exit_module+0x1c/0xd50 [ixgbe] [ 148.576430] __do_sys_delete_module.isra.0+0x1bc/0x2e0 [ 148.576446] do_syscall_64+0x7f/0x980 It can be reproduced by trying to unload ixgbe driver in recovery mode.
