...ir(path). This obviously fails for relative names. That could be fixed by using opendir(".") instead. However, if multiple relative directory names are given, this would still fail after the first such directory. Instead, leave the current directory unchanged and use the fstatat() and readlinkat() functions to get information about files in each directory.

I ran the Coverity static analyzer[1] on libguestfs, and fixed many errors as a result. Coverity found some errors in gnulib, but it doesn't seem to be worth following those up since the version of gnulib we are using is so old. There are a couple more errors (possibly 1 false-positive) which I'm going to send in a separate email. BTW all the errors found by Coverity were in the daemon

Hello, This series introduces arm64 support to klibc. I've rebased the work from Neil Williams and Anil Singhar into the following three patches. Most of the code changes are due to new syscall implementations being needed for arm64 as a only a minimal set of syscalls are defined in the arm64 kernel. This series is to be applied against the latest klibc, just after 25a66fa README.klibc:

The previously selected 'atomic' recipe resulted in 2GB swap in a 6GB volume. Also, we don't really need the boot partition, so just create a partition using the whole disk space. --- builder/templates/debian.preseed | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) diff --git a/builder/templates/debian.preseed b/builder/templates/debian.preseed index

Hello, Here is V2 of the arm64 support for klibc patch set. Notable changes since the original series: * fp regs dropped from setjmp/longjmp * chmod, lstat and stat re-implemented with *at functions. * open64 merged into open. As with the original, this series is to be applied against the latest klibc, just after 25a66fa README.klibc: update build information V2 has been tested on x86_64

Commit 0a94cae15bae7cecb725e78e485708694d347612 added useful headings to parts of the configure script. This refactors the code by adding a common macro (‘HEADING’), and also changes the output so it's clearer at a glance: --- Checking for Haskell --- checking for ghc...

This is an extended version of: https://www.redhat.com/archives/libguestfs/2019-September/msg00178.html It adds a couple of simple code changes, so it makes it possible to drop more modules. In addition, more unused modules were dropped. Pino Toscano (5): tests: switch away from xgetcwd daemon: move read_whole_file to common utils daemon: switch from read_file to read_whole_file daemon:
