Bug ID: 19922
Summary: [PATCH] iso14651_t1_common: Define collation for
Malayalam chillu characters
Product: glibc
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: localedata
Assignee: unassigned at sourceware dot org
Reporter: santhosh.thottingal at gmail dot com
CC: libc-locales at sourceware dot org

iso14651_t1_common: define collation for Malayalam chillu characters
Malayalam Chillu characters, that were added in Unicode 5.1 is not considered
in the collation rules for Malayalam. These 6 characters are
U+07DA to U+07DF
Unicode defines them as alternate representation of ZWJ based Chillus
(Consonant+Virama+ZWJ). ZWJ based chillus are represented in the collation
rules already.
So U+07DA to U+07DF should have primary collation weight equal to the ZWJ
based Chillus. Note that ZWJ has 0 collation weight(ignorable in collation).
So:
U+07DA(ൺ) and U+0D23(ണ)+ U+0D4D(്) have same primary weight and differs in
secondary level weight.
Unicode CLDR collation also follows exactly same logic. See
http://unicode.org/cldr/trac/browser/trunk/common/collation/ml.xml
[...]
# Pre-5.1 Chillus secondary equal to 5.1 chillus.
# Chillus primary equal to their consonant_dead form.
&ക്<<ക്\u200D<<<ൿ
&ണ്<<ണ്\u200D<<<ൺ
&ന്<<ന്\u200D<<<ൻ
&ര്<<ര്\u200D<<<ർ
&ല്<<ല്\u200D<<<ൽ
&ള്<<ള്\u200D<<<ൾ
[...]
The attached patch implements this.
To test, have a text file with following content:
ണ്
ണ്
ൺ
$ LANG=ml_IN.UTF-8 sort ~/sort.txt
ണ്
ണ്
ൺ
The same input can be tested with
http://demo.icu-project.org/icu-bin/collation.html and verify the output is
same as the above output.
Explanation of output:
1. ണ\u0D4D - This is ണ + ്
2. ണ\u0D4D\u200D - This is ണ + ് + ZWJ - ZWJ based chillu. Sorts after the ZWJ
less dead form of ണ.
3. ൺ - This is atomic chillu ൺ U+07DA - with secondary level collation weight
differing from above ZWJ based chillu.

--- Comment #2 from Pravin S <pravin.d.s at gmail dot com> ---
Verified patch, it applies clean. Giving expected results.
Thank you Santhosh for this patch.
Atomic Chillu U+0D7A-U+0D7F are in Unicode from 5.1 version and it is important
to have sorting support for this in Glibc.

Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.

CVE-2017-1000366: Ignore LD_LIBRARY_PATH for AT_SECURE=1 programs [BZ
#21624]
LD_LIBRARY_PATH can only be used to reorder system search paths, which
is not useful functionality.
This makes an exploitable unbounded alloca in _dl_init_paths unreachable
for AT_SECURE=1 programs.
