Change in ...nfs-ganesha[next]: MDCACHE - Add MDCACHE {} config block

Issues seen with krb5i and krb5p mounts

by Trishali Nayar

Hi all, There are a few clients eg- Ubuntu 18.04.3 (4.15.0-55-generic) and RH7.8 (3.10.0-1127.el7.x86_64) for which we have observed... simple command like 'dd' either hangs or returns EIO. This is happening only on krb5i and krb5p mounts. It seems to happen for file sizes eg- 100MB and larger mostly. But sometimes even a 30 MB file sees failures. A client eg- RH7.6 (3.10.0-957.el7.x86_64) does not seem to hit this issue...so might be with more recent kernels? We fixed the issue with check-in https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/490802 The idea was to let clients know that Ganesha denied the request VS just dropping the request. This fix did seem to help and hangs/errors stopped completely... but for larger file sizes eg- 1000MB we started seeing "Permission Denied" errors. This was different than the EIO errors seen earlier. Reason could be we are now sending an "AUTH DENIED" error so clients translate it to this new error. We tried to add more logging into Ganesha and observe that these particular clients seem to send a lot of requests together. When we process same, the sequence no. is pretty much out or order and we drop the requests outside the sequence window, as per the RFC 2203 Section 7.2.1. The sequence window that we have is 32. Testing these clients with kNFS does not hit the issue...The kNFS sequence window seems to be larger and is 128. So, tried to increase the sequence window as well to 128 for ganesha. That does not seem to help fix the issue. We also have below additional 'seqmask' check and many of the requests went into that category as well and were dropped. "libntirpc/src/svc_auth_gss.c": } else if (offset >= gd->win || (gd->seqmask & (1 << offset))) { *no_dispatch = true; goto gd_free; } Also observed that now these clients sent many requests above the 128 window...which we would again drop. Wondering what is the proper way to fix this and any idea on what these clients are doing different. Thanks and regards, Trishali. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Trishali Nayar IBM Systems ETZ, Pune. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

lseek gets bad offset from nfs client with ganesha/gluster which supports SEEK

by Kinglong Mee

The latest ganesha/gluster supports seek according to, https://tools.ietf.org/html/draft-ietf-nfsv4-minorversion2-41#section-15.11 From the given sa_offset, find the next data_content4 of type sa_what in the file. If the server can not find a corresponding sa_what, then the status will still be NFS4_OK, but sr_eof would be TRUE. If the server can find the sa_what, then the sr_offset is the start of that content. If the sa_offset is beyond the end of the file, then SEEK MUST return NFS4ERR_NXIO. For a file's filemap as, Part 1: HOLE 0x0000000000000000 ---> 0x0000000000600000 Part 2: DATA 0x0000000000600000 ---> 0x0000000000700000 Part 3: HOLE 0x0000000000700000 ---> 0x0000000001000000 SEEK(0x700000, SEEK_DATA) gets result (sr_eof:1, sr_offset:0x70000) from ganesha/gluster; SEEK(0x700000, SEEK_HOLE) gets result (sr_eof:0, sr_offset:0x70000) from ganesha/gluster. If an application depends the lseek result for data searching, it may enter infinite loop. while (1) { next_pos = lseek(fd, cur_pos, seek_type); if (seek_type == SEEK_DATA) { seek_type = SEEK_HOLE; } else { seek_type = SEEK_DATA; } if (next_pos == -1) { return ; cur_pos = next_pos; } The lseek syscall always gets 0x70000 from nfs client for those two cases, but, if underlying filesystem is ext4/f2fs, or the nfs server is knfsd, the lseek(0x700000, SEEK_DATA) gets ENXIO. I wanna to know, should I fix the ganesha/gluster as knfsd return ENXIO for the first case? or should I fix the nfs client to return ENXIO for the first case? thanks, Kinglong Mee
