ext4: fix error handling in ext4_restore_inline_data()

2022-02-08T17:16:30Z

commit 897026aaa73eb2517dfea8d147f20ddb0b813044 upstream. While running "./check -I 200 generic/475" it sometimes gives below kernel BUG(). Ideally we should not call ext4_write_inline_data() if ext4_create_inline_data() has failed. [73131.453234] kernel BUG at fs/ext4/inline.c:223!


 212 static void ext4_write_inline_data(struct inode *inode, struct ext4_iloc *iloc,
 213                                    void *buffer, loff_t pos, unsigned int len)
 214 {
<...>
 223         BUG_ON(!EXT4_I(inode)->i_inline_off);
 224         BUG_ON(pos + len > EXT4_I(inode)->i_inline_size);

This patch handles the error and prints out a emergency msg saying potential
data loss for the given inode (since we couldn't restore the original
inline_data due to some previous error).

EDAC/xgene: Fix deferred probing
2022-02-08T17:16:30Z
commit dfd0dfb9a7cc04acf93435b440dd34c2ca7b4424 upstream.

The driver overrides error codes returned by platform_get_irq_optional()
to -EINVAL for some strange reason, so if it returns -EPROBE_DEFER, the
driver will fail the probe permanently instead of the deferred probing.
Switch to propagating the proper error codes to platform driver code
upwards.

rtc: cmos: Evaluate century appropriate

commit ff164ae39b82ee483b24579c8e22a13a8ce5bd04 upstream.

There's limiting the year to 2069. When setting the rtc year to 2070,
reading it returns 1970. Evaluate century starting from 19 to count the
correct year.

selftests: futex: Use variable MAKE instead of make
2022-02-08T17:16:29Z
commit b9199181a9ef8252e47e207be8c23e1f50662620 upstream.

Recursive make commands should always use the variable MAKE, not the
explicit command name ‘make’. This has benefits and removes the
following warning when multiple jobs are used for the build:

make[2]: warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.

nfsd: nfsd4_setclientid_confirm mistakenly expires confirmed client.
2022-02-08T17:16:29Z
commit ab451ea952fe9d7afefae55ddb28943a148247fe upstream.

From RFC 7530 Section 16.34.5:

o  The server has not recorded an unconfirmed { v, x, c, *, * } and
   has recorded a confirmed { v, x, c, *, s }.  If the principals of
   the record and of SETCLIENTID_CONFIRM do not match, the server
   returns NFS4ERR_CLID_INUSE without removing any relevant leased
   client state, and without changing recorded callback and
   callback_ident values for client { x }.

The current code intends to do what the spec describes above but
it forgot to set 'old' to NULL resulting to the confirmed client
to be expired.

scsi: bnx2fc: Make bnx2fc_recv_frame() mp safe

commit 936bd03405fc83ba039d42bc93ffd4b88418f1d3 upstream.

modifying the per_cpu lport stats counters in a non-mpsafe way.  Just boot
a debug kernel and run the bnx2fc driver with the hardware enabled.
