Objects built from assembly get an executable stack by default. The file has a stanza to make the stack non-executable, but on non-amd64 architectures this stanza is skipped together with the rest of the file. Nevertheless, it seems that even the empty file causes an executable stack to be created. To avoid the issue, do a build with the assembler file explicitly skipped. --- zstd.spec | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) diff --git a/zstd.spec b/zstd.spec index 964c3c7..145a3e5 100644 --- a/zstd.spec +++ b/zstd.spec @@ -4,10 +4,12 @@ %else %ifarch %{ix86} x86_64 %bcond_without pzstd +%bcond_without asm %else # aarch64 and armv7hl at least currently segfault # in ThreadPool test for the pzstd util %bcond_with pzstd +%bcond_with asm %endif %endif @@ -22,11 +24,12 @@ Source0: https://github.com/facebook/zstd/archive/v%{version}.tar.gz#/%{n Patch1: pzstd.1.patch -BuildRequires: make +BuildRequires: make BuildRequires: gcc gtest-devel %if %{with pzstd} BuildRequires: gcc-c++ %endif +BuildRequires: execstack %description Zstd, short for Zstandard, is a fast lossless compression algorithm, @@ -62,14 +65,16 @@ find -name .gitignore -delete %build export CFLAGS="$RPM_OPT_FLAGS" export LDFLAGS="$RPM_LD_FLAGS" -%make_build -C lib lib-mt -%make_build -C programs +%make_build -C lib lib-mt %{!?with_asm:ZSTD_NO_ASM=1} +%make_build -C programs %{!?with_asm:ZSTD_NO_ASM=1} %if %{with pzstd} export CXXFLAGS="$RPM_OPT_FLAGS" -%make_build -C contrib/pzstd +%make_build -C contrib/pzstd %{!?with_asm:ZSTD_NO_ASM=1} %endif %check +execstack lib/libzstd.so.1 + export CFLAGS="$RPM_OPT_FLAGS" export LDFLAGS="$RPM_LD_FLAGS" make -C tests test-zstd @@ -121,6 +126,10 @@ install -D -m644 programs/%{name}.1 %{buildroot}%{_mandir}/man1/p%{name}.1 %ldconfig_scriptlets -n lib%{name} %changelog +* Tue Dec 28 2021 Zbigniew Jędrzejewski-Szmek - 1.5.1-1 +- Disable amd64 assembly on non-intel architectures (#2035802): + this should avoid the issue where an executable stack is created. + * Wed Dec 22 2021 Pádraig Brady - 1.5.1-1 - Latest upstream From 1862b14f48f6a3736659ee88ac4a82e974742b2a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Tue, 28 Dec 2021 17:39:12 +0100 Subject: [PATCH 04/29] Bump release --- zstd.spec | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/zstd.spec b/zstd.spec index 145a3e5..88a01ae 100644 --- a/zstd.spec +++ b/zstd.spec @@ -15,7 +15,7 @@ Name: zstd Version: 1.5.1 -Release: 1%{?dist} +Release: 2%{?dist} Summary: Zstd compression library License: BSD and GPLv2 @@ -126,7 +126,7 @@ install -D -m644 programs/%{name}.1 %{buildroot}%{_mandir}/man1/p%{name}.1 %ldconfig_scriptlets -n lib%{name} %changelog -* Tue Dec 28 2021 Zbigniew Jędrzejewski-Szmek - 1.5.1-1 +* Tue Dec 28 2021 Zbigniew Jędrzejewski-Szmek - 1.5.1-2 - Disable amd64 assembly on non-intel architectures (#2035802): this should avoid the issue where an executable stack is created.

It also features a very fast decoder, with speeds > 500 MB/s per core, which remains roughly stable at all compression settings\.

+ \fB\-M#\fR, \fB\-\-memory=#\fR
+ Limit the amount of sample data loaded for training (default: 2 GB)\. Note that the default (2 GB) is also the maximum\. This parameter can be useful in situations where the training set size is not well controlled and could be potentially very large\. Since speed of the training process is directly correlated to the size of the training sample set, a smaller sample set leads to faster training\.
++.
+ .IP
+ In situations where the training set is larger than maximum memory, the CLI will randomly select samples among the available ones, up to the maximum allowed memory budget\. This is meant to improve dictionary relevance by mitigating the potential impact of clustering, such as selecting only files from the beginning of a list sorted by modification date, or sorted by alphabetical order\. The randomization process is deterministic, so training of the same list of files with the same parameters will lead to the creation of the same dictionary\.
++.
+ .TP
+ \fB\-\-dictID=#\fR
+-A dictionary ID is a locally unique ID\. The decoder will use this value to verify it is using the right dictionary\. By default, zstd will create a 4\-bytes random number ID\. It's possible to provide an explicit number ID instead\. It's up to the dictionary manager to not assign twice the same ID to 2 different dictionaries\. Note that short numbers have an advantage: an ID < 256 will only need 1 byte in the compressed frame header, and an ID < 65536 will only need 2 bytes\. This compares favorably to 4 bytes default\.

+ \fB\-\-train\-cover[=k#,d=#,steps=#,split=#,shrink[=#]]\fR
+ Select parameters for the default dictionary builder algorithm named cover\. If \fId\fR is not specified, then it tries \fId\fR = 6 and \fId\fR = 8\. If \fIk\fR is not specified, then it tries \fIsteps\fR values in the range [50, 2000]\. If \fIsteps\fR is not specified, then the default value of 40 is used\. If \fIsplit\fR is not specified or split <= 0, then the default value of 100 is used\. Requires that \fId\fR <= \fIk\fR\. If \fIshrink\fR flag is not used, then the default value for \fIshrinkDict\fR of 0 is used\. If \fIshrink\fR is not specified, then the default value for \fIshrinkDictMaxRegression\fR of 1 is used\.
++.
+ .IP
+ Selects segments of size \fIk\fR with highest score to put in the dictionary\. The score of a segment is computed by the sum of the frequencies of all the subsegments of size \fId\fR\. Generally \fId\fR should be in the range [6, 8], occasionally up to 16, but the algorithm will run faster with d <= \fI8\fR\. Good values for \fIk\fR vary widely based on the input data, but a safe range is [2 * \fId\fR, 2000]\. If \fIsplit\fR is 100, all input samples are used for both training and testing to find optimal \fId\fR and \fIk\fR to build dictionary\. Supports multithreading if \fBzstd\fR is compiled with threading support\. Having \fIshrink\fR enabled takes a truncated dictionary of minimum size and doubles in size until compression ratio of the truncated dictionary is at most \fIshrinkDictMaxRegression%\fR worse than the compression ratio of the largest dictionary\.

+ Same as cover but with extra parameters \fIf\fR and \fIaccel\fR and different default value of split If \fIsplit\fR is not specified, then it tries \fIsplit\fR = 75\. If \fIf\fR is not specified, then it tries \fIf\fR = 20\. Requires that 0 < \fIf\fR < 32\. If \fIaccel\fR is not specified, then it tries \fIaccel\fR = 1\. Requires that 0 < \fIaccel\fR <= 10\. Requires that \fId\fR = 6 or \fId\fR = 8\.
++.
+ .IP
+ \fIf\fR is log of size of array that keeps track of frequency of subsegments of size \fId\fR\. The subsegment is hashed to an index in the range [0,2^\fIf\fR \- 1]\. It is possible that 2 different subsegments are hashed to the same index, and they are considered as the same subsegment when computing frequency\. Using a higher \fIf\fR reduces collision but takes longer\.

+ \fB\-\-train\-legacy[=selectivity=#]\fR
+ Use legacy dictionary builder algorithm with the given dictionary \fIselectivity\fR (default: 9)\. The smaller the \fIselectivity\fR value, the denser the dictionary, improving its efficiency but reducing its achievable maximum size\. \fB\-\-train\-legacy=s=#\fR is also accepted\.
