bit-rot xlator: strncpy()->sprintf(), reduce strlen()'s 2018-08-31T01:36:34+00:00 Yaniv Kaul ykaul@redhat.com 2018-08-21T16:20:25+00:00 4b5e3c347cfb80e4749f1963e25d1dd93563f784 xlators/features/bit-rot/src/bitd/bit-rot-scrub-status.c xlators/features/bit-rot/src/stub/bit-rot-stub-helpers.c xlators/features/bit-rot/src/stub/bit-rot-stub.c xlators/features/bit-rot/src/stub/bit-rot-stub.h strncpy may not be very efficient for short strings copied into a large buffer: If the length of src is less than n, strncpy() writes additional null bytes to dest to ensure that a total of n bytes are written.

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.

Instead, use snprintf(). Ensure sprintf() results do not
truncate.

Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN or sizeof() for const strings.
- move ret from int32 to int.

Compile-tested only!

feature/bitrot: remove internal xattrs from lookup cbk 2017-12-19T04:26:02+00:00 Ravishankar N ravishankar@redhat.com 2017-12-11T10:44:03+00:00 d341f20230b9921391aff22337eaf9be82f44d88 Problem: afr requests all xattrs in lookup via the list-xattr key. If bitrot is enabled and later disabled, or if the bitrot xattrs were present due to an older version of bitrot which used to create the xattrs without enabling the feature, the xattrs (trusted.bit-rot.version in particular) was not getting filtered and ended up reaching the client stack. AFR, on noticing different values of the xattr across bricks of the replica, started triggering spurious metadata heals. Fix: Filter all internal xattrs in bitrot xlator before unwinding lookup, (f)getxattr. Thanks to Kotresh for the help in RCA'ing.
