Bug ID: 16538
Summary: Missing underflow exception from sinl
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: zimmerma+gcc at loria dot fr
on x86_64:
Testing function sin for exponent 0 [seed=8344].
rounding mode MPFR_RNDZ:
wrong underflow flag for x=8.0000000000000000@-4112
library gives 8.0000000000000000@-4112
mpfr gives 0
underflow: mpfr 1, library 0
Since the glibc result is the smallest subnormal 0x1p-16445, an underflow
exception should be raised.

idem in double precision (on x86_64):
Testing function sin for exponent 0 [seed=17940].
rounding mode MPFR_RNDD:
wrong underflow flag for x=4.0000000000000@-269
library gives 4.0000000000000@-269
mpfr gives 0
underflow: mpfr 1, library 0
This is the smallest subnormal 0x1p-1074.

commit ad39cce0da0161dba69781c53349acf2e23f156c
Author: Joseph Myers <joseph@codesourcery.com>
Date: Tue Jun 23 22:24:20 2015 +0000
Fix sin, sincos missing underflows (bug 16526, bug 16538).
Similar to various other bugs in this area, some sin and sincos
implementations do not raise the underflow exception for subnormal
arguments, when the result is tiny and inexact. This patch forces the
exception in a similar way to previous fixes.
Tested for x86_64, x86, mips64 and powerpc.

Bug ID: 18588
Summary: crypt "leaks" ENOENT
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: akshay.moghe at gmail dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Running:
--------
Linux 3.13.0-55-generic on Fedora release 22 (Twenty Two)
GNU C Library (GNU libc) stable release version 2.21
Compiled by GNU CC version 5.0.0 20150217 (Red Hat 5.0.0-0.15).
Issue
-----
On a successful call to crypt_r using a salt that employs the use of SHA512
("$6$saltedsalted6464$") even when the function returns a valid hash, the errno
is set to ENOENT. Presumably this is due to the fips check (failing because of
missing proc entry).
One can make a case for this errno to be cleared on successful execution of the
function.
