Summary
RDMA/core: Fix null-ptr-deref in ib_core_cleanup()
Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/core: Fix null-ptr-deref in ibcorecleanup()

KASAN reported a null-ptr-deref error:

KASAN: null-ptr-deref in range [0x0000000000000118-0x000000000000011f] CPU: 1 PID: 379 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) RIP: 0010:destroyworkqueue+0x2f/0x740 RSP: 0018:ffff888016137df8 EFLAGS: 00000202 ... Call Trace: ibcorecleanup+0xa/0xa1 [ibcore] _dosysdeletemodule.constprop.0+0x34f/0x5b0 dosyscall64+0x3a/0x90 entrySYSCALL64afterhwframe+0x63/0xcd RIP: 0033:0x7fa1a0d221b7 ...

It is because the fail of rocegidmgmt_init() is ignored:

ibcoreinit() rocegidmgmtinit() gidcachewq = allocorderedworkqueue # fail ... ibcorecleanup() rocegidmgmtcleanup() destroyworkqueue(gidcache_wq) # destroy an unallocated wq

Fix this by catching the fail of rocegidmgmtinit() in ibcore_init().
