Change in ...nfs-ganesha[next]: coverity: string is not null terminated (do not merge)

by Kaleb KEITHLEY (GerritHub)

Kaleb KEITHLEY has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/458987 Change subject: coverity: string is not null terminated (do not merge) ...................................................................... coverity: string is not null terminated (do not merge) Now with utf8string_dup(). But do not merge because this adds more coverity warnings than it fixes. Fixes an issue (of sorts) reported by coverity, namely not enough memory is allocated to store a terminating NULL in a utf8string. The warning is a false positive. utf8strings in ganesha are nominally strings that come off the wire and may or may not be null terminated; given that, it is not safe to call strlen(). Furthermore, they need not be NULL terminated when stored internally as the length is stored in an associated length variable. In this case the string comes from an xattr and should contain a ':' separator. The ':' separator, if there is one, is replaced with a null by strsep(). By convention it should still be considered not safe to call strlen() or (gsh_)strdup(), but gsh_strdup() is used everywhere else in ganesha for utf8strings, so we do it here as well. Foolish consistency and all that. At least we know it's safe here. And it should silence the coverity warning. Unfortunately simply adding a /* coverity[OVERRUN] */ comment here did not silence it.

Change in ...nfs-ganesha[next]: MDCACHE - delay invalidate of dir for whence-is-name

by Daniel Gryniewicz (GerritHub)

MDCACHE - delay invalidate of dir for whence-is-name A directory invalidate on a whence-is-name FSAL is a potentially huge performance problem. It can cause the entire directory to reload to find the correct cookie, which can time out the client if the directory is large. To avoid this, put of the invalidate as long as active readdirs are in process. Note, this has no effect on upcalls, so an upcall can still invalidate the directory.

Change in ...nfs-ganesha[next]: MDCACHE - add a name-cookie mapping for whence-is-name

by Daniel Gryniewicz (GerritHub)

Daniel Gryniewicz has uploaded this change for review.

MDCACHE - add a name-cookie mapping for whence-is-name Restarting a readdir internally because the chunk containing the requested cookie has been reaped cause extreme performance problems on large directories. It can cause a hang long enough for the client to time out. To avoid this, add a name-cookie map. This map contains the last cookie we sent to a client, so that when that cookie is sent back by the client, we can look up the name even if the chunk containing that dirent has been reaped. This map is in an LRU, with a hard cap (Dirmap_HWMark), and it's cleaned up in the background if entries are older than 60 seconds. Notet that we also save the second cookie in the set, since the linux client seems to request that one approximately 1/3 of the time.
