Re: warning in nfsd4_cb_done

Hi,

We're currently running 6.12.13 with the following 4 patches on top:

1. 1b3e26a5ccbfc2f85bda1930cc278e313165e353: NFSD: fix decoding in nfs4_xdr_dec_cb_getattr

This patch went into 6.13-rc7, but I don't think it was CC'ed to stable?
I also don't see it in nfsd-6.12.y branch on https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git/log
Is it not needed on 6.12?

2. cedfbb92cf97a6bff3d25633001d9c44442ee854: NFSD: fix hang in nfsd4_shutdown_callback

This one is now in 6.12.16

3. 99e98a2312c8d08fba60d548009c03e7cfb1bf6b: NFSD: Skip sending CB_RECALL_ANY when the backchannel isn't up

This one seems to have a CC: stable but I assume it's not yet there as it isn't included in the mainline kernel yet? Is it expected to be merged into 6.14-rcX, or will it have to wait for 6.15?

4. 4990d098433db18c854e75fb0f90d941eb7d479e: NFSD: Fix CB_GETATTR status fix

This one seems to be in 6.14-rc, but also doesn't have a CC: stable? It fixes 1b3e26a5ccbfc2f85bda1930cc278e313165e353 above.


Are there any plans to include these patches in the 6.12.y kernel?

Some of the patches mentioned above are in the nfsd-{fixes,testing,next} branches on https://git.kernel.org/pub/scm/linux/kernel/git/cel/linux.git, but I don't know what all of these branches are used for. Is the nfsd-next branch what's expected to land in the next upstream kernel (6.15-rc1), or also the current rc kernels (6.14-rcX)?

What is the difference between the nfsd-testing and nfsd-fixes branch?


This kernel seems to be running stable for now, but it's too soon to conclude it fixes the issue that sometimes comes up. It does show the following kernel message sometimes:

rpc-srv/tcp: nfsd: sent 106256 when sending 131204 bytes - shutting down socket

I don't recall seeing this message with previous (6.11 and earlier) kernels. Does this message mean a single connection to a client was shut down? Is this a message we can ignore?

Regards,
Rik
