* [PATCH] fix Module taint flags listing in Oops/panicFlorin Malita2006-10-111-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | Module taint flags listing in Oops/panic has a couple of issues: * taint_flags() doesn't null-terminate the buffer after printing the flags * per-module taints are only set if the kernel is not already tainted (with that particular flag) => only the first offending module gets its taint info correctly updated Some additional changes: * 'license_gplok' is no longer needed - equivalent to !(taints & TAINT_PROPRIETARY_MODULE) - so we can drop it from struct module * exporting module taint info via /proc/module: pwc 88576 0 - Live 0xf8c32000 evilmod 6784 1 pwc, Live 0xf8bbf000 (PF) Signed-off-by: Florin Malita <fmalita@gmail.com> Cc: "Randy.Dunlap" <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] list module taint flags in Oops/panicRandy Dunlap2006-10-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | When listing loaded modules during an oops or panic, also list each module's Tainted flags if non-zero (P: Proprietary or F: Forced load only). If a module is did not taint the kernel, it is just listed like usbcore but if it did taint the kernel, it is listed like wizmodem(PF) Example: [ 3260.121718] Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: [ 3260.121729] [<ffffffff8804c099>] :dump_test:proc_dump_test+0x99/0xc8 [ 3260.121742] PGD fe8d067 PUD 264a6067 PMD 0 [ 3260.121748] Oops: 0002 [1] SMP [ 3260.121753] CPU 1 [ 3260.121756] Modules linked in: dump_test(P) snd_pcm_oss snd_mixer_oss snd_seq snd_seq_device ide_cd generic ohci1394 snd_hda_intel snd_hda_codec snd_pcm snd_timer snd ieee1394 snd_page_alloc piix ide_core arcmsr aic79xx scsi_transport_spi usblp [ 3260.121785] Pid: 5556, comm: bash Tainted: P 2.6.18-git10 #1 [Alternatively, I can look into listing tainted flags with 'lsmod', but that won't help in oopsen/panics so much.] [akpm@osdl.org: cleanup] Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] /sys/modules: allow full length section namesIan S. Nelson2006-09-291-2/+2
| | | | | | | | | | | | I've been using systemtap for some debugging and I noticed that it can't probe a lot of modules. Turns out it's kind of silly, the sections section of /sys/module is limited to 32byte filenames and many of the actual sections are a a bit longer than that.

* [SCSI] MODULE_FIRMWARE for binary firmware(s)Jon Masters2006-08-301-0/+5
| | | | | | | | | | | | | | | | | | | | | | Right now, various kernel modules are being migrated over to use request_firmware in order to pull in binary firmware blobs from userland when the module is loaded. This makes sense. However, there is right now little mechanism in place to automatically determine which binary firmware blobs must be included with a kernel in order to satisfy the prerequisites of these drivers. This affects vendors, but also regular users to a certain extent too. The attached patch introduces MODULE_FIRMWARE as a mechanism for advertising that a particular firmware file is to be loaded - it will then show up via modinfo and could be used e.g. when packaging a kernel.

* [PATCH] null-terminate over-long /proc/kallsyms symbolsAndreas Gruenbacher2006-07-141-6/+4
| | | | | | | | | | | | | | | | | Got a customer bug report (https://bugzilla.novell.com/190296) about kernel symbols longer than 127 characters which end up in a string buffer that is not NULL terminated, leading to garbage in /proc/kallsyms. Using strlcpy prevents this from happening, even though such symbols still won't come out right. A better fix would be to not use a fixed-size buffer, but it's probably not worth the trouble. (Modversion'ed symbols even have a length limit of 60.)

* [PATCH] Add EXPORT_UNUSED_SYMBOL and EXPORT_UNUSED_SYMBOL_GPLArjan van de Ven2006-06-281-0/+20
| | | | | | | | | | | | | | | | Temporarily add EXPORT_UNUSED_SYMBOL and EXPORT_UNUSED_SYMBOL_GPL. These will be used as a transition measure for symbols that aren't used in the kernel and are on the way out. When a module uses such a symbol, a warning is printk'd at modprobe time. The main reason for removing unused exports is size: eacho export takes roughly between 100 and 150 bytes of kernel space in the binary. This patch gives users the option to immediately get this size gain via a config option.

* [PATCH] modules: add version and srcversion to sysfsMatt Domsch2005-06-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds version and srcversion files to /sys/module/${modulename} containing the version and srcversion fields of the module's modinfo section (if present). /sys/module/e1000 |-- srcversion `-- version This patch differs slightly from the version posted in January, as it now uses the new kstrdup() call in -mm. Why put this in sysfs? a) Tools like DKMS, which deal with changing out individual kernel modules without replacing the whole kernel, can behave smarter if they can tell the version of a given module. The autoinstaller feature, for example, which determines if your system has a "good" version of a driver (i.e. if the one provided by DKMS has a newer verson than that provided by the kernel package installed), and to automatically compile and install a newer version if DKMS has it but your kernel doesn't yet have that version. b) Because sysadmins manually, or with tools like DKMS, can switch out modules on the file system, you can't count on 'modinfo foo.ko', which looks at /lib/modules/${kernelver}/... actually matching what is loaded into the kernel already. Hence asking sysfs for this. c) as the unbind-driver-from-device work takes shape, it will be possible to rebind a driver that's built-in (no .ko to modinfo for the version) to a newly loaded module. sysfs will have the currently-built-in version info, for comparison. d) tech support scripts can then easily grab the version info for what's running presently - a question I get often. There has been renewed interest in this patch on linux-scsi by driver authors. As the idea originated from GregKH, I leave his Signed-off-by: intact, though the implementation is nearly completely new. Compiled and run on x86 and x86_64.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+570
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
