2018-12-24net: dccp: fix kernel crash on module loadPeter Oskolkov
Patch eedbbb0d98b2 "net: dccp: initialize (addr,port) ..." added calling to inet_hashinfo2_init() from dccp_init(). However, inet_hashinfo2_init() is marked as __init(), and thus the kernel panics when dccp is loaded as module. Removing __init() tag from inet_hashinfo2_init() is not feasible because it calls into __init functions in mm. This patch adds inet_hashinfo2_init_mod() function that can be called after the init phase is done; changes dccp_init() to call the new function; un-marks inet_hashinfo2_init() as exported.

2018-12-24drivers/net: appletalk/cops: remove redundant if statement and maskColin Ian King
The two different assignments for pkt_len are actually the same and so the if statement is redundant and can be removed. Masking a u8 return value from inb() with 0xFF is also redundant and can also be emoved. Similarly, the two different outb calls are identical as the mask of 0xff on the second outb is redundant since a u8 is being written, so the if statement is also redundant and can be also removed. Detected by CoverityScan, CID#1475639 ("Identical code for different branches") V2: Remove the if statement for the outb calls, thanks to David Miller for spotting this.

2018-12-24pwm: imx: Add ipg clock operationAnson Huang
i.MX PWM module's ipg_clk_s is for PWM register access, on most of i.MX SoCs, this ipg_clk_s is from system ipg clock or perclk which is always enabled, but on i.MX7D, the ipg_clk_s is from PWM1_CLK_ROOT which is controlled by CCGR132, that means the CCGR132 MUST be enabled first before accessing PWM registers on i.MX7D. This patch adds ipg clock operation to make sure register access successfully on i.MX7D and it fixes Linux kernel boot up hang during PWM driver probe.

2018-12-23CIFS: Fix error mapping for SMB2_LOCK command which caused OFD lock problemGeorgy A Bystrenin
While resolving a bug with locks on samba shares found a strange behavior. When a file locked by one node and we trying to lock it from another node it fail with errno 5 (EIO) but in that case errno must be set to (EACCES | EAGAIN). This isn't happening when we try to lock file second time on same node. In this case it returns EACCES as expected. Also this issue not reproduces when we use SMB1 protocol (vers=1.0 in mount options). Further investigation showed that the mapping from status_to_posix_error is different for SMB1 and SMB2+ implementations. For SMB1 mapping is [NT_STATUS_LOCK_NOT_GRANTED to ERRlock] (See fs/cifs/netmisc.c line 66) but for SMB2+ mapping is [STATUS_LOCK_NOT_GRANTED to -EIO] (see fs/cifs/smb2maperror.c line 383) Quick changes in SMB2+ mapping from EIO to EACCES has fixed issue.

2018-12-23crypto: skcipher - remove remnants of internal IV generatorsEric Biggers
Remove dead code related to internal IV generators, which are no longer used since they've been replaced with the "seqiv" and "echainiv" templates. The removed code includes: - The "givcipher" (GIVCIPHER) algorithm type. No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG. Just hardcode "<default>" or "<none>" in those cases. - The 'skcipher_givcrypt_request' structure, which is never used.
