2018-02-25ISDN: eicon: reduce stack size of sig_ind functionArnd Bergmann1-8/+8
commit 27d807180ae0a9e50d90adf9b22573c21be904c2 upstream. I noticed that this function uses a lot of kernel stack when the "latent entropy" plugin is enabled: drivers/isdn/hardware/eicon/message.c: In function 'sig_ind': drivers/isdn/hardware/eicon/message.c:6113:1: error: the frame size of 1168 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] We currently don't warn about this, as we raise the warning limit to 2048 bytes in mainline, but I'd like to lower that limit again in the future, and this function can easily be changed to be more efficient and avoid that warning, by making some of its local variables 'const'.

2017-02-01ISDN: eicon: silence misleading array-bounds warningArnd Bergmann1-1/+2
commit 950eabbd6ddedc1b08350b9169a6a51b130ebaaf upstream. With some gcc versions, we get a warning about the eicon driver, and that currently shows up as the only remaining warning in one of the build bots: In file included from ../drivers/isdn/hardware/eicon/message.c:30:0: eicon/message.c: In function 'mixer_notify_update': eicon/platform.h:333:18: warning: array subscript is above array bounds [-Warray-bounds] The code is easily changed to open-code the unusual PUT_WORD() line causing this to avoid the warning.

2015-02-03isdn: off by one in connect_res()Dan Carpenter1-1/+1
The bug here is that we use "Reject" as the index into the cau_t[] array in the else path. Since the cau_t[] has 9 elements if Reject == 9 then we are reading beyond the end of the array. My understanding of the code is that it's saying that if Reject is 1 or too high then that's invalid and we should hang up.

2015-01-12isdn: fix NUL (\0 or \x00) specification in stringGiel van Schijndel1-1/+1
In C one can either use '\0' or '\x00' (or '\000') to add a NUL byte to a string. '\0x00' isn't part of these and will in fact result in a single NUL followed by "x00". This fixes that.

isdn source code uses a not-current coding style. Update the coding style used on a per-line basis so that git diff -w shows only elided blank lines at EOF.

2010-03-16i4l: silence compiler warnings for array access in Eicon DIVA ISDN driverIan Munsie1-8/+7
When compiling this driver, the compiler throws the following warnings: drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds This arises from the particular semantics the driver is using to write to the nlc array (static byte[256]). The array has a length in byte 0 followed by a T30_INFO struct starting at byte 1. The T30_INFO struct has a number of variable length strings after the station_id entry, which cannot be explicitly defined in the struct and the driver accesses them with an array index to station_id beyond the length of station_id. This patch merely changes the semantics that the driver uses to access the entries after the station_id entry to use the original 256 byte nlc array taking the offset and length of the station_id entry to calculate where to write in the array, thereby silencing the warning.

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!
