Security updates for Friday
Security updates have been issued by Debian (expat and mupdf), Fedora (drupal7-uuid, php-brumann-polyfill-unserialize, and php-typo3-phar-stream-wrapper2), openSUSE (thunderbird), Oracle (thunderbird and vim), SUSE (glibc), and Ubuntu (poppler). | | 3:26p |
[$] The io.weight I/O-bandwidth controller Part of the kernel's job is to arbitrate access to the available hardware resources and ensure that every process gets its fair share, with "its fair share" being defined by policies specified by the administrator. One resource that must be managed this way is I/O bandwidth to storage devices; if due care is not taken, an I/O-hungry process can easily saturate a device, starving out others. The kernel has had a few I/O-bandwidth controllers over the years, but the results have never been entirely satisfactory. But there is a new
controller on the block that might just get the job done. | | 11:43p |
Cook: package hardening asymptote On his blog, Kees Cook looks at some graphs of package hardening efforts in Ubuntu and Debian, noting that they have nearly completely flattened out over the last few years. He wonders what might be the next hardening feature on the horizon and speculates some on that: " What new compiler feature adoption could be measured? I think there are still a few good candidates…
How about enabling -fstack-clash-protection (only in GCC, Clang still hasn’t implemented it).
Or how about getting serious and using forward-edge Control Flow Integrity? (Clang has -fsanitize=cfi for general purpose function prototype based enforcement, and GCC has the more limited -fvtable-verify for C++ objects.)
Where is backward-edge CFI? (Is everyone waiting for CET?)" | | 11:51p |
FreeDOS turns 25 years old: An origin story (Opensource.com) Over on Opensource.com, FreeDOS founder Jim Hall writes about the origin of the MS-DOS replacement on the 25th anniversary of FreeDOS. " While I announced the project as PD-DOS (for "public domain," although the abbreviation was meant to mimic IBM's "PC-DOS"), we soon changed the name to Free-DOS and later FreeDOS.
I started working on it right away. First, I shared the utilities I had written to expand the DOS command line. Many of them reproduced MS-DOS features, including CLS, DATE, DEL, FIND, HELP, and MORE. Some added new features to DOS that I borrowed from Unix, such as TEE and TRCH (a simple implementation of Unix's tr). I contributed over a dozen FreeDOS utilities
By sharing my utilities, I gave other developers a starting point. And by sharing my source code under the GNU General Public License (GNU GPL), I implicitly allowed others to add new features and fix bugs." |
