home [2019/01/14 10:34] – adminhome [2024/10/29 09:22] (current) – New request types GET_XATTR and MODIFY_XATTR on FD targets ao
Line 1: Line 1:
-==== RSBAC ported to 4.19 ====+== New request types GET_XATTR and MODIFY_XATTR on FD targets == 
 +//Tuesday, 29/Oct/2024// 
 + 
 +The system call families getxattr() and setxattr() used to be intercepted with requests GET_PERMISSIONS_DATA and MODIFY_PERMISSIONS_DATA. Since extended attributes do much more than Linux access control with ACLs, we needed a way to distinguish these types of access. 
 + 
 +I decided to introduce the new request types GET_XATTR and MODIFY_XATTR for them, valid for all FD targets. The changes are in the kernel Git repos for 6.6, 6.1, 5.15 and 5.10 as well as in the rsbac-admin repo for administration. Older kernels remain unchanged. 
 + 
 +== RSBAC stable with kernel 6.6 == 
 +//Wednesday, 26/Jun/2024// 
 + 
 +RSBAC with kernel 6.6 is now recommended. It has been running very well for months. 
 + 
 +== RSBAC for kernel 6.6 == 
 +//Thursday, 11/Jan/2024// 
 + 
 +RSBAC has been ported successfully to LTS kernel 6.6. Internal kernel changes to the Linux caps structure required new on-disk versions of all RSBAC lists holding cap vectors. 
 + 
 +I took the chance to default CONFIG_RSBAC_MOVETO to yes with 6.6 and auto-adjust RC and ACL FD lists with new versions, too. Existing WRITE right to FD targets gets amended with MOVETO during list upgrade to avoid unexpected behaviour. 
 + 
 +The automatic list version upgrades mean that going back to previous kernels might show invalid lists, you need to boot with rsbac_list_recover kernel parameter and set cap related and RC and ACL FD values again. 
 + 
 +In my tests, 6.6 seems to be running pretty well, please give it a try and report. Patches are at https://download.rsbac.org/latestdiff/6.6/ 
 + 
 +== RSBAC very stable with kernel 6.1 == 
 +//Wednesday, 04/Oct/2023// 
 + 
 +Hi folks, 
 + 
 +just a quick note that kernel 6.1 has been running very well with RSBAC for months now, I recommend switching to 6.1. 
 + 
 +As usual, you get all the code at https://download.rsbac.org/latestdiff/ or through Git at git.rsbac.org/, e.g. git.rsbac.org/linux-6.1.y 
 + 
 + 
 +== RSBAC 1.5.6 for kernel 6.1 == 
 +//Wednesday, 15/Feb/2023// 
 + 
 +Hi folks, 
 + 
 +RSBAC has been ported to kernel 6.1 at 5.15 state. Seems to be running fine on my test system, but please test yourself and report to the mailing list or to the bug tracker. 
 + 
 +You get all the code at https://download.rsbac.org/latestdiff/ or through Git at git.rsbac.org/, e.g. git.rsbac.org/linux-6.1.y 
 + 
 +RSBAC has been running very well with kernel series 5.10 for a long time, so please consider 5.10 to be the best choice for now. 
 + 
 + 
 +== RSBAC 1.5.6 for kernel 5.15 == 
 +//Tuesday, 09/Nov/2021// 
 + 
 +Hi folks, 
 + 
 +just a quick notice that RSBAC has been ported to kernel 5.15 at 5.10 state. Seems to be running fine on my test system, but please test yourself and report here or to the bug tracker. 
 + 
 +In 1.5.6, found in 5.15, 5.10 and rsbac-admin Git repos, we have a new IPC target memfd, which lets memfd access be treated as IPC for easier administration. 
 + 
 +You get all the code at https://download.rsbac.org/latestdiff/ or through Git at git.rsbac.org/, e.g. git.rsbac.org/linux-5.15.y 
 + 
 +RSBAC has been running very well with kernel series 5.10 for a long time, so please consider 5.10 to be the best choice for now. 
 + 
 + 
 +== RSBAC for kernel 5.10 == 
 +//Thursday, 31/Dec/2020// 
 + 
 +RSBAC is now available for kernel 5.10. So far it seems to work 
 +fine here. Please test and report bugs to the bugtracker at 
 +https://bugtracker.rsbac.org or to this list. 
 + 
 +As usual, you find the latest patches at 
 +https://download.rsbac.org/latestdiff/5.10/ 
 +and the Git repo at 
 +https://git.rsbac.org/cgi-bin/gitweb.cgi?p=linux-5.10.y.git;a=summary 
 + 
 +As we are heading into 2021, we wish all of you a good and successful new 
 +year. RSBAC development will turn 25 years old in 2021, maybe a good 
 +time for some celebration and reflection. 
 + 
 +== Decision modules PAX and DAZ removed == 
 +//Wednesday, 22/Apr/2020// 
 + 
 +PAX and DAZ modules have been removed in latest kernel 5.4 and 
 +rsbac-admin git repos. RSBAC version is now 1.5.5 to reflect that change. 
 + 
 +== Deprecate decision modules PAX and DAZ == 
 +//Tuesday, 31/Mar/2020// 
 + 
 +PAX and DAZ support are now marked as deprecated. PaX has not been freely available for years and the Dazuko interface seems obsolete, too. For on-access malware scanning, I recommend the UDF module. 
 + 
 +If noone protests within the next few weeks, I am going to remove the related code. 
 + 
 +== RSBAC for kernel 5.4 == 
 +//Wednesday, 27/Nov/2019// 
 + 
 +RSBAC has been ported to kernel 5.4. Please test and report bugs to the bugtracker at https://bugtracker.rsbac.org or to this list. 
 + 
 +As usual, you find the latest patches at https://download.rsbac.org/latestdiff/5.4/ and the Git repo at https://git.rsbac.org/cgi-bin/gitweb.cgi?p=linux-5.4.y.git;a=summary 
 + 
 +== New DokuWiki version == 
 +//Monday, 14/Jan/2019// 
 + 
 +The RSBAC Website DokuWiki version has been updated today. 
 + 
 +Please test and report any problems!

 +== RSBAC 1.5.0 ==
 +//Tuesday, 13/September/2016//
 +
 +[[:download|RSBAC 1.5.0]] has been released for kernel 4.4.20. Please drop us a note if you need support for other kernel versions.
 +
 +The most important changes since 1.4.9 are the port to longterm kernel 4.4 and the new feature "Prevent memory write and execute (RSBAC mprotect)" to prevent against process memory segments being both writable and executable. This new hardening feature made me choose a new middle version number.
 +
 +The change lists are here:
