Re: [S] Change in ...nfs-ganesha[next]: fixed coverity issue 275287 (dead code) by ifdefing out the unused code

by Frank Filz

I’m going to cc: the devel mailing list for more opinions This code looks (mostly) safe to me. The concern I have is that it isn’t using gsh_malloc and gsh_free yet I assume that the buffer when freed later is freed with gsh_free. Frank From: Paul Moyer [mailto:Paul.Moyer@ibm.com] Sent: Friday, November 4, 2022 7:55 AM To: Frank Filz <ffilzlnx(a)mindspring.com> Subject: RE: [S] Change in ...nfs-ganesha[next]: fixed coverity issue 275287 (dead code) by ifdefing out the unused code After looking at this closer I don’t think it is a problem: In function ‘xdr_utf8string_decode’, inlined from ‘inline_xdr_utf8string’ at /home/moyer/275287/nfs-ganesha/src/include/nfsv41.h:4055:3, inlined from ‘decode_acl’ at /home/moyer/275287/nfs-ganesha/src/Protocols/NFS/nfs_proto_tools.c:834:29: /home/moyer/275287/nfs-ganesha/src/include/nfsv41.h:4041:8: warning: attempt to free a non-heap object ‘buffer’ [-Wfree-nonheap-object] free(sp); ^ looking at the code (snipets) 3991 static inline bool 3992 xdr_utf8string_decode(XDR *xdrs, utf8string *objp, u_int maxsize) 3993 { 3994 /* sp is the actual string pointer */ 3995 char *sp = objp->utf8string_val; 4026 if (!sp) { 4027 sp = (char *)malloc(size + 1); 4036 ret = xdr_opaque_decode(xdrs, sp, size); 4038 if (!ret) { 4039 if (!objp->utf8string_val) { 4040 /* Only free if we allocated */ 4041 free(sp); 4042 } 4043 return ret; 4044 } 4045 4046 objp->utf8string_val = sp; /* only valid po inter */ so the flow seems to be: sp is a pointer assigned to a string inside obj which is passed as a parameter if sp is null, malloc is called and sp now points to “locally” allocated space if an error occurs in xdr_opaque_decode(), enter the error path starting at 4038 if the string (in the passed object) that sp was originally assigned to is null, sp is free'd therefore, sp is only malloc'ed if the original string is null, and if the original string is null, sp is free'd which is consistent with the comment on 4040, though the logic took some study ... the pointer in the passed object is subsequently replaced with sp: if the pointer was not null to begin with, sp would already point to the same string if the pointer was null, memory would be allocated and the passed object would be updated with a pointer to the “locally” allocated memory i think this works because this method is declared as "static inline", so the allocated memory is ultimately local to the caller anyway ?
