Bug ID: 31080
Summary: strerrorname_np and strerror don't know about ENOSYM
and EREMOTERELEASE on Linux/hppa
Product: glibc
Version: 2.37
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: bruno at clisp dot org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Created attachment 15225
--> https://sourceware.org/bugzilla/attachment.cgi?id=15225&action=edit
test case foo.c
The function strerrorname_np is supposed to return non-NULL for all defined
errno values.
https://www.gnu.org/software/libc/manual/html_node/Error-Messages.html
On Linux/hppa, for the errnos with names
ENOSYM
EREMOTERELEASE
it returns NULL.
$ grep -rw ENOSYM /usr/include
/usr/include/asm/errno.h:#define ENOSYM 215 /* symbol does not
exist in executable */
$ grep -rw EREMOTERELEASE /usr/include
/usr/include/asm/errno.h:#define EREMOTERELEASE 240 /* Remote peer
released connection */
How to reproduce:
$ gcc -Wall foo.c
$ ./a.out
Expected output:
strerrorname_np (ENOSYM) = "ENOSYM"
strerrorname_np (EREMOTERELEASE) = "EREMOTERELEASE"
strerror (ENOSYM) = Symbol does not exist in executable
strerror (EREMOTERELEASE) = Remote peer released connection
Actual output:
strerrorname_np (ENOSYM) = (null)
strerrorname_np (EREMOTERELEASE) = (null)
strerror (ENOSYM) = Unknown error 215
strerror (EREMOTERELEASE) = Unknown error 240
Seen on T2-SDE Linux, with glibc 2.37.

--- Comment #1 from Adhemerval Zanella <adhemerval.zanella at linaro dot org> ---
This is because they are not defined or described in the error codes [1]. They
also seem not to be returned by the kernel, so not sure how useful adding these
would be for hppa-linux-gnu.

Indeed.
Then you could ask the kernel people to remove these two errnos from
linux/arch/parisc/include/uapi/asm/errno.h. Similar to what has been done with
ENOTSUP in
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/arch/parisc/include/uapi/asm/errno.h?id=93cb8e20d56be40c541475f77b5f565fbb385a4b

I've added a kernel patch to the for-next branch to remove those from parisc's
errno.h file:

Thanks! That looks exactly like what is needed.
