SELinux file permissions
Hi,
I'm trying to grant dovecot the ability to manage its socket within
the postfix spool directory.
I have added the below to file_contexts.local :
/var/spool/postfix/private/dovecot-auth system_u:system_r:dovecot_t:s0
However, running "restorecon -v
/var/spool/postfix/private/dovecot-auth" gives me the following error
:

SELinux file permissions
Thanks for the pointer, will take a look down that route.
Could you confirm the below is expected behaviour on Centos ?
# semanage fcontext -a -t my_postfixauth_private_t
"/var/spool/postfix/private(/.*)?"
ValueError: Type my_postfixauth_private_t is invalid, must be a file
or device type

libvirt and UEFI/SecureBoot
Hi!
I'm working currently on integration of UEFI/SecureBoot support into
oVirt. And I have several questions about UEFI/SecureBoot support in
libvirt. Can you please help me with them?
For UEFI I add the following to the XML:
<loader readonly="yes" secure="no" type="pflash">
/usr/share/OVMF/OVMF_CODE.secboot.fd

Discard .note.gnu.property section to fix build failure (patch)
Hi,
currently syslinux fails to build from source in Debian as has been
reported in https://bugs.debian.org/906414 . The reported error is:
mbr.bin: too big (452 > 440)
I've realized that this is because since a recent version, the linker
adds a new section (.note.gnu.property). Discarding this section fixes
the problem. I've attached a patch, please consider merging it.
Thanks

Using syslinux.efi while doing UEFI HTTP boot iso PXE boot
Hi,
We are currently testing PXE booting with syslinux.efi in UEFI mode.
This is working fine.
However the loading of syslinux.efi and the config files is still using
TFTP protocol, the rest kernel and initrd is loaded using HTTP protocol.
We would like to use only HTTP protocol.
In UEFI it is possible to use HTTP boot instead off PXE boot.
Questions:
1. If we load syslinux.efi with HTTP will

Some (U)EFI questions
Hi everyone,
for UEFI bootable media I currently use preloader+gummiboot while on
BIOS media I use isolinux/extlinux. Since maintaining two configurations
is some kind of extra work, I plan switching to syslinux in the next
weeks or months. Creating an UEFI boot partition or El-Torito image
seems easy: Use preloader, hashtool and the syslinux efi file, copy them
to the FAT image and be

Boot another *.efi from SYSLinux?
Hi!
I am currently trying upgrade my bios pxe server with additional uefi support.
My current using memtest86+ doesn't seem to support uefi, so I would have to use memtest86, as it supports this.
But the memtest86 file itself is an *.efi file. When booting this one directly without syslinux, its working.
But I want to launch it later from the syslinux menu. Can I chainload somehow another

SELinux file permissions
Hello,
restorecon works only for existing files, for new files you are looking for
file transition rule.
Google that out, there is plenty of articles on that topic, for example:

Not as much as you
may think.? We already have lwIP implemented into lpxelinux.0.? It's more a matter of using more glue.

HP Envy EFI problem after BIOS update
I had to boot my HP Envy into Win8 for the first time in ages this morning.
When I did that, it installed some updates including a BIOS update.
Once this was all done, once again the GRUB boot menu was gone and it booted
straight into Win8. Using the advanced boot manager options in Win8 I
managed to get the EFI boot menu up and chose Ferdora 21.
It was only after Fedora failed to boot that
