2020-11-15overall usermode...: Fix Lesser GPL version numberChetan Pant1-1/+1
There is no "version 2" of the "Lesser" General Public License. It is either "GPL version 2.0" or "Lesser GPL version 2.1". This patch replaces all occurrences of "Lesser GPL version 2" with "Lesser GPL version 2.1" in comment section.

2020-08-27linux-user: Add strace support for printing arguments for ioctls used for ↵Filip Bozuta1-9/+14
terminals and serial lines Functions "print_ioctl()" and "print_syscall_ret_ioctl()" are used to print arguments of "ioctl()" with "-strace". These functions use "thunk_print()", which is defined in "thunk.c", to print the contents of ioctl's third arguments that are not basic types. However, this function doesn't handle ioctls of group ioctl_tty which are used for terminals and serial lines. These ioctls use a type "struct termios" which thunk type is defined in a non standard way using "STRUCT_SPECIAL()". This means that this type is not decoded regularly using "thunk_convert()" and uses special converting functions "target_to_host_termios()" and "host_to_target_termios()", which are defined in "syscall.c" to decode it's values. For simillar reasons, this type is also not printed regularly using "thunk_print()". That is the reason why a separate printing function "print_termios()" is defined in file "strace.c". This function decodes and prints flag values of the "termios" structure. Implementation notes: Function "print_termios()" was implemented in "strace.c" using an existing function "print_flags()" to print flag values of "struct termios" fields. Also, recently implemented function "print_enums()" was also used to print enumareted values which are contained in the fields of 'struct termios'. These flag values were defined using an existing macro "FLAG_TARGET()" that generates aproppriate target flag values and string representations of these flags. Also, the recently defined macro "ENUM_TARGET()" was used to generate aproppriate enumarated values and their respective string representations. Function "print_termios()" was declared in "qemu.h" so that it can be accessed in "syscall.c". Type "StructEntry" defined in "exec/user/thunk.h" contains information that is used to decode structure values. Field "void print(void *arg)" was added in this structure as a special print function. Also, function "thunk_print()" was changed a little so that it uses this special print function in case it is defined. This printing function was instantiated with the defined "print_termios()" in "syscall.c" in "struct_termios_def".

2020-07-04linux-user: Add strace support for printing arguments of ioctl()Filip Bozuta1-0/+154
This patch implements functionality for strace argument printing for ioctls. When running ioctls through qemu with "-strace", they get printed in format: "ioctl(fd_num,0x*,0x*) = ret_value" where the request code an the ioctl's third argument get printed in a hexadicemal format. This patch changes that by enabling strace to print both the request code name and the contents of the third argument. For example, when running ioctl RTC_SET_TIME with "-strace", with changes from this patch, it gets printed in this way: "ioctl(3,RTC_SET_TIME,{12,13,15,20,10,119,0,0,0}) = 0" In case of IOC_R type ioctls, the contents of the third argument get printed after the return value, and the argument inside the ioctl call gets printed as pointer in hexadecimal format. For example, when running RTC_RD_TIME with "-strace", with changes from this patch, it gets printed in this way: "ioctl(3,RTC_RD_TIME,0x40800374) = 0 ({22,9,13,11,5,120,0,0,0})" In case of IOC_RW type ioctls, the contents of the third argument get printed both inside the ioctl call and after the return value. Implementation notes: Functions "print_ioctl()" and "print_syscall_ret_ioctl()", that are defined in "strace.c", are listed in file "strace.list" as "call" and "result" value for ioctl. Structure definition "IOCTLEntry" as well as predefined values for IOC_R, IOC_W and IOC_RW were cut and pasted from file "syscall.c" to file "qemu.h" so that they can be used by these functions to print the contents of the third ioctl argument. Also, the "static" identifier for array "ioctl_entries[]" was removed and this array was declared as "extern" in "qemu.h" so that it can also be used by these functions. To decode the structure type of the ioctl third argument, function "thunk_print()" was defined in file "thunk.c" and its definition is somewhat simillar to that of function "thunk_convert()".

2016-06-07thunk: Drop unused NO_THUNK_TYPE_SIZE guardsPeter Maydell1-2/+0
The thunk_type_size_array() and thunk_type_align_array() functions are only provided if NO_THUNK_TYPE_SIZE is not defined. However nothing in the codebase defines that, and so in fact these functions are always present. Drop the unnecessary #ifdefs. (Over a decade ago thunk.h used to be included by some softmmu files, which defined NO_THUNK_TYPE_SIZE, but these includes are long gone; see for instance commit f193c7979c2f7.)

2015-06-15linux-user: Allocate thunk size dynamicallyAlexander Graf1-4/+12
We store all struct types in an array of static size without ever checking whether we overrun it. Of course some day someone (like me in another, ancient ALSA enabling patch set) will run into the limit without realizing it. So let's make the allocation dynamic. We already know the number of structs that we want to allocate, so we only need to pass the variable into the respective piece of code. Also, to ensure we don't accidently overwrite random memory, add some asserts to sanity check whether a thunk is actually part of our array.
