Hi,

I am running into this compile error in 5.15.171 in OpenWrt on 32 bit systems. This problem was introduced with kernel 5.15.169.

fs/udf/namei.c: In function 'udf_rename':
fs/udf/namei.c:878:1: error: the frame size of 1144 bytes is larger than
1024 bytes [-Werror=frame-larger-than=]
   878 | }
       | ^
cc1: all warnings being treated as errors
make[2]: *** [scripts/Makefile.build:289: fs/udf/namei.o] Error 1
make[1]: *** [scripts/Makefile.build:552: fs/udf] Error 2

This is fixed by this upstream commit: commit 0aba4860b0d0216a1a300484ff536171894d49d8 Author: Jan Kara jack@suse.cz Date: Tue Dec 20 12:38:45 2022 +0100

 udf: Allocate name buffer in directory iterator on heap

Please backport this patch to 5.15 too. It was already backported to kernel 6.1.

I tried to take it as-is, but it broek the build. Can you please submit a tested version that actually works?

thanks,

greg k-h

Hi,

I just noticed that it does no compile on x86, I only tested it on MIPS and there it compiles.

I already have a fixed version will send it soon.
