2020-05-15staging: greybus: uart: replace driver line-coding structJohan Hovold1-15/+4
Drop the driver version of the line-coding request and use the protocol definition directly as was originally intended instead. This specifically avoids having the two versions of what is supposed to be the same struct ever getting out of sync. Note that this has in fact already happened once when the protocol definition had its implicit padding removed while the driver struct wasn't updated. The fact that we used the size of the then larger driver struct when memcpying its content to the stack didn't exactly make things better. A later addition of a flow-control field incidentally made the structures match again.

2020-05-13staging: greybus: Fix uninitialized scalar variableOscar Carter1-2/+2
In the "gb_tty_set_termios" function the "newline" variable is declared but not initialized. So the "flow_control" member is not initialized and the OR / AND operations with itself results in an undefined value in this member. The purpose of the code is to set the flow control type, so remove the OR / AND self operator and set the value directly.

2020-03-17staging: greybus: loopback_test: fix potential path truncationsJohan Hovold1-7/+8
Newer GCC warns about possible truncations of two generated path names as we're concatenating the configurable sysfs and debugfs path prefixes with a filename and placing the results in buffers of the same size as the maximum length of the prefixes. snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id); snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/", t->sysfs_prefix, d->name); snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s", t->debugfs_prefix, d->name); Fix this by separating the maximum path length from the maximum prefix length and reducing the latter enough to fit the generated strings. Note that we also need to reduce the device-name buffer size as GCC isn't smart enough to figure out that we ever only used MAX_STR_LEN bytes of it.

2020-02-23staging: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

2019-09-03staging: greybus: light: fix a couple double freesDan Carpenter1-6/+6
The problem is in gb_lights_request_handler(). If we get a request to change the config then we release the light with gb_lights_light_release() and re-allocated it. However, if the allocation fails part way through then we call gb_lights_light_release() again. This can lead to a couple different double frees where we haven't cleared out the original values: gb_lights_light_v4l2_unregister(light); ... kfree(light->channels); kfree(light->name); I also made a small change to how we set "light->channels_count = 0;". The original code handled this part fine and did not cause a use after free but it was sort of complicated to read.
